+Release 1.14.2 (2014-03-09 Bryce Harrington <bryce@osg.samsung.com>)
+====================================================================
+This release provides collected bug fixes, along with one feature
+enhancement for the xcb backend, and a small performance improvement for
+fonts.
+
+The running theme of the bug fixes is platform-specific issues, both
+build and run-time. Platforms with fixes include Sparc, AIX, Windows
+(mingw), and Windows (MSVC8). Memory leaks, valgrind issues, and PDF
+issues round out our list.
+
+It's come to light that changes in cairo 1.14 resulted in breakage on
+MacOS X 10.4. We've not yet determined whether to fix up the support,
+or excise the 10.4-specific code and support only OS X 10.5 or newer.
+Meantime, we'll only advertise cairo as working on OS X 10.5.
+
+Features
+--------
+ * Improve xcb's handling of per-screen subpixel ordering. If no
+ Xft.rgba property is specified, default to the screen's subpixel
+ order.
+
+API Changes
+-----------
+None
+
+Dependency Changes
+------------------
+None
+
+Performance Optimizations
+-------------------------
+ * Improve performance of cpu_to_be32 and be32_to_cpu, making truetype
+ subsetting of large fonts run about 15% faster.
+
+Bug Fixes
+---------
+ * Fix unaligned access on sparc with the compact font format (CFF).
+ Unlike truetype, all data in CFF is not aligned.
+ (Debian bug #712836)
+ * Fix unaligned access on sparc with tor-scan-converter's memory pool.
+ * Fix crash when loading a PDF with a transformed image.
+ (fdo bug #85151)
+ * Fix regression on mingw for bigendian test due to removal of file
+ extension for executables.
+ (fdo bug #85120)
+ * Fix handling of backslash in PDF interpreter
+ (fdo bug #85662)
+ * Fix crash in xlib and xcb renderers when swapping a 0-sized glyph
+ * Fix bug with RTL text in PDF operators
+ (fdo bug #86461)
+ * Fix compilation 'cairo-path-stroke-traps.c' with MSVC8
+ (fdo bug #84908)
+ * Fix crash in _fill_xrgb32_lerp_opaque_spans when a span length is
+ negative.
+ * Fix valgrind error by releasing pattern created by
+ cairo_pattern_create_rgb().
+ * Fix valgrind errors when running cairo-test-suite.
+ * Fix memory leak in recording surface replays
+ (fdo bug #87898)
+ * Fix destruction of fonts in api-special-cases test.
+ (fdo bug #87567)
+ * Fix duplicated surface push on similar-image, preventing trivial GTK3
+ program traces from being replayable, with an error message about
+ invalid values for the size of the input.
+ (fdo bug #73580)
+ * Fix crash when win32 surface's image size does not cover the entire
+ surface.
+ (fdo bug #53121)
+ * Fix crash due to obsolete CGFontGetGlyphPath call
+ (fdo bug #84324)
+ * Fix several build issues on AIX
+ (fdo bugs #89338, #89340, #89356, #89354)
+ * Fix various documentation warnings and errors
+
+Release 1.14.0 (2014-10-13 Bryce Harrington <bryce@osg.samsung.com>)
+====================================================================
+Hard to believe it's been over a year since our last release, but it's
+not for lack of activity. This release includes contributions of a wide
+assortment of bug fixes, build system improvements, warnings cleanups,
+codebase refactoring, test suite repairs, and static analysis work.
+
+This release is lighter on features (compared with 1.12.10) but includes
+a highly demanded rehaul of our image downscaling functionality, which
+solves a serious problem experienced by Inkscape users when shrinking
+embedded bitmaps in SVG files. The new scaling algorithms are used by
+the image backend and by other backends as needed for fallbacks.
+
+
+Features
+--------
+
+ Filtering improvements for the image backend, in particular
+ down-scaling of images produces filtered images that depend on all the
+ pixels of the source. When using the image backend you get the
+ following settings:
+
+ CAIRO_FILTER_GOOD: uses a box filter for scales less than .75 in
+ either direction. For scales larger than this, the same filter as
+ CAIRO_FILTER_BILINEAR is used.
+
+ CAIRO_FILTER_BEST: uses a Catmull-Rom filter always. When upscaling
+ more than 2x this will produce anti-aliased square pixels, similar
+ to OS/X.
+
+ CAIRO_FILTER_GAUSSIAN: uses PIXMAN_FILTER_BEST, which in current
+ pixman is the same as BILINEAR. (This is subject to change in the
+ future).
+
+ xlib and xcb also use the image fallback for GOOD/BEST filters, but
+ note that other backends do not implement these filtering fixes yet,
+ however other actions may cause them to use an image fallback which
+ will cause these filters to be used.
+
+ Improve handling of device transformation and scaling, allowing Cairo
+ to now support scaling at a device level, permitting easier, more
+ transparent HiDPI support.
+
+ Support JBIG2 mime data in PDF. This allows embedding of more
+ compressed JPEG formats within PDF, rather than including the full
+ uncompressed image. Also, reduce the number of transparency groups
+ used by PDF to keep the file size small and viewing/printing of the
+ PDF fast.
+
+ Expand the embedding section to include stencil mask support.
+
+ Reorder font declarations to be in natural order.
+
+ Update the Skia backend to build against current Skia (as of June
+ 2014).
+
+ Drop Link-Time Optimization (LTO) support from build system. This
+ seems to have caused much trouble for unclear benefit, and most
+ distros are reverting or disabling it anyway.
+
+ Optimize VBO size on GL to 1M and to 16k for EGL. This improves
+ (theoretical) performance for desktop GLX use cases while avoiding
+ hitting VBO memory size limitations on embedded devices.
+
+API Changes
+-----------
+
+ cairo_surface_set_device_scale, cairo_surface_get_device_scale:
+
+ Sets a scale that is multiplied to the device coordinates
+ determined by the CTM when drawing to @surface. One common use for
+ this is to render to very high resolution display devices at a scale
+ factor, so that code that assumes 1 pixel will be a certain size
+ will still work.
+
+ cairo_egl_device_get_display, cairo_egl_device_get_context:
+
+ Support get/set of EGLContext and EGLDisplay for egl-based cairo
+ devices, similar to GLX.
+
+Dependency Changes
+------------------
+
+ Cairo now requires glib 2.14 for its gobject helper functions,
+ and pixman 0.30 for downscaling.
+
+
+Bug fixes
+---------
+
+ Don't embed CMYK Jpeg images in svg.
+
+ Fix tests to place output in proper location.
+
+ Fix determination of alpha for all surfaces when recording.
+
+ Extend oversize check to cairo_gl_surface_create_for_texture, so an
+ error surface is returned if the texture is too large to render to.
+
+ Fix embedding of mime data in PDF and PS files.
+
+ Remove useless error handling in *_reply() functions in XCB.
+
+ Fix a double-free exposed by multithreaded apps creating and
+ destroying the same font concurrently.
+ https://bugs.freedesktop.org/show_bug.cgi?id=69470
+
+ Fix corrupt stacks produced by bugs in operand emission for trace.
+
+ Fix out of bounds array access in format cache for xlib
+
+ Don't rename glyphs used by seac operator. This can cause certain
+ combined characters to use their decorations (e.g. umlauts on ö) to be
+ lost during printing of PDFs using evince.
+ https://bugs.freedesktop.org/show_bug.cgi?id=70364
+
+ Fix crash on calling cairo_create with a finished surface
+
+ Fix SSIZE_T definition problem when making with MSYS on Windows7
+
+ Fix one off issue in gl context cleanup
+
+ Fix usage of CAIRO_STACK_ARRAY_LENGTH
+
+ Fix rectangle stroke with non rectilinear pen
+
+ Fix imagemask with pattern source failure on some printers. This bug
+ could cause files converted using pdftops to fail for example on Ricoh
+ printers, or opening in Adobe Distiller on Windows.
+ https://bugs.freedesktop.org/show_bug.cgi?id=69485
+
+ Fix whitespace in font names
+
+ Fix page size in generated PDFs. When printing using pdftocairo on
+ larger page sizes, such as 11x17, the image would be cropped to letter
+ size.
+ https://bugs.freedesktop.org/show_bug.cgi?id=73452
+
+ Fix path-currentpoint test by preserving current-point in
+ copy_path()/append_path() sequence
+
+ Fix generation of HTML in code docs for
+ cairo-format-stride-for-width. Raw HTML code was being passed
+ to the browser, instead of displaying normally.
+ https://bugs.freedesktop.org/show_bug.cgi?id=63257
+
+ Fix spelling of "tessellator" throughout code. We're using the
+ American rather than British spelling of this word.
+ https://bugs.freedesktop.org/show_bug.cgi?id=50411
+
+ Fix crash in pixman_image_composite32
+
+ Fix crash when trying to modify a (const) all-clipped cairo_clip_t
+ https://bugs.freedesktop.org/show_bug.cgi?id=75819

Release 1.12.14 (2013-02-10 Chris Wilson <chris@chris-wilson.co.uk>)
===================================================================
In the last week we had a few more bugs reported and promptly resolved.
of edges generated by the general stroker.
As part of the focus on performance, Cairo 1.12 introduces some
-antialias hints (NONE,FAST, GOOD, BEST) that are interpolated by the
-raserisers to fine tune their performance versus quality. Cairo 1.12
+antialias hints (NONE, FAST, GOOD, BEST) that are interpolated by the
+rasterisers to fine tune their performance versus quality. Cairo 1.12
also introduces a new observation architecture,
cairo_surface_observer_t, which can be used to analyse the amount of
time consumed by drawing commands and help identify inefficiencies in
"platform" backends which depend on some underlying platform-specific
system, (such as the X Window System or some other window system).
-As an example, for a standard Linux build, (with image, png, pdf,
-PostScript, svg, and xlib surface backends, and the freetype font
-backend), the following sample commands will install necessary

+As an example, for a standard Linux build similar to what's shipped by
+your distro, (with image, png, pdf, PostScript, svg, and xlib surface
+backends, and the freetype font backend), the following sample commands
+will install necessary dependencies:
Debian (and similar):
- apt-get install libpng12-dev libz-dev libxrender-dev libfontconfig1-dev
+ apt-get build-dep cairo
Fedora (and similar):
yum install libpng-devel zlib-devel libXrender-devel fontconfig-devel
-(Those commands intentionally don't install pixman from a distribution

-to grab pixman from the same place at the same time and compile it as
-well.)
+Technically you probably don't need pixman from the distribution since
+if you're manually compiling Cairo you probably want an updated pixman
+as well. However, if you follow the default settings and install pixman
+to /usr/local, your Cairo build should properly use it in preference to
+the system pixman.

Supported, "standard" surface backends
------------------------------------
image backend (required)
------------------------
- pixman >= 0.20.2 http://cairographics.org/releases
+ pixman >= 0.30.0 http://cairographics.org/releases
png support (can be left out if desired, but many
----------- applications expect it to be present)
quartz backend
--------------
- MacOS X >= 10.4 with Xcode >= 2.4
+ MacOS X >= 10.5 with Xcode >= 3.0
win32 backend
-------------
packages and developer dependencies are available at Netlabs:

+
Compiling
=========
See the INSTALL document for build instructions.
+
History
=======
Cairo was originally developed by Carl Worth <cworth@cworth.org> and
1) Ensure that there are no local, uncommitted/unpushed
modifications. You're probably in a good state if both "git diff
- HEAD" and "git log master..origin/master" give no output.
+ HEAD" and "git log master..origin/master" give no output. Also make
+ sure you have libglib2.0-doc installed (else you'll get excessive
+ gtk-doc cross reference warnings in the next step).
2) Verify that the code passes "make distcheck"
8) Push the newly created tag out to the central tree with a command
something like:
- git push cairo X.Y.Z
+ git push origin master X.Y.Z
9) Edit the cairo bugzilla product and add the new version numbers. Note
that you need to add two versions. One for the release/snapshot (with
odd micro version).
10) Send a message to cairo-announce@cairographics.org and CC
- gnome-announce-list@gnome.org and ftp-release@lists.freedesktop.org
- (pr@lwn.net as well for major releases) to announce the new release
- using the text provided from "make release-publish", adding the excerpt
- from NEWS, your signature, followed by the standard "What is cairo" and
- "Where to get more information about cairo" blurbs from README, and
- finally the shortlog of all changes since last release, generated by:
+ cairo@cairographics.org, gnome-announce-list@gnome.org and
+ ftp-release@lists.freedesktop.org (pr@lwn.net as well for major
+ releases) to announce the new release using the text provided from
+ "make release-publish", adding the excerpt from NEWS, your
+ signature, followed by the standard "What is cairo" and "Where to
+ get more information about cairo" blurbs from README, and finally
+ the shortlog of all changes since last release, generated by:
git shortlog X.Y.Z...
11) Edit the cairo wiki to add the announcement to the NEWS page and
the front page. (just the parts before your signature).
-12) For minor releases (no X.Y change), notify desktop-devel-list@gnome.org
- or update the ExternalDependencies page for the current cycle if you
- know where it is. Currently it's:
-
- http://live.gnome.org/TwoPointNineteen/ExternalDependencies

+Welcome to the cairo tutorial:
+
++--------------------------------+
+| How to Recognize Ugly Graphics |
+|(and what you can do about them)|
++--------------------------------+
+
+This directory is your personal playground for following along with
+the examples. In order for you to make use of these files you will
+need to have cairo and its header files installed. You can find
+instructions for doing this at:
+
+ http://cairographics.org/tutorial
+
+Notice that there are a few .c files in this directory.
+
+You should start out by just typing "make" which will turn each .c
+file into several different programs. Go ahead and run each of the
+programs and see what they do. Some of them will open up new X windows
+while others will simply write their output to files (such .png or
+.pdf).
+
+After you play with those a bit, go ahead and take a look at the
+contents of the .c files. You'll see that each file contains a draw()
+function that does all of the drawing.
+
+You might be surprised to notice that there is no main() function in
+any of the files. Instead, main is hidden away by means of
+cairo-tutorial.h. This rather non-conventional style is used to allow
+you to focus on the actual drawing code involved in using cairo, while
+not having to worry about the setup semantics. We don't recommend that
+you follow this style for real projects.
+
+As you follow along during the tutorial and get some ideas for things
+to draw, you'll want to start making your own .c files. You can copy
+an existing file or make your own by following this simple minimal
+template:
+
+ #include "cairo-tutorial.h"
+
+ static void
+ draw (cairo_t *cr, int width, int height)
+ {
+ /* Put your drawing code here. */
+ }
+
+Any new file you create will automatically get picked up by the
+Makefile so that "make" will compile your file into several different
+programs, just like the existing examples.
+
+If you'd like to control the initial size of the output, you may
+define WIDTH and HEIGHT before including cairo-tutorial.h like so:
+
+ #define WIDTH 100
+ #define HEIGHT 100
+
+ #include "cairo-tutorial.h"
+
+If you would like to change the set of cairo-backend target programs
+that are compiled, you may edit the "all" target in the Makefile.
+
+Have fun!

+which will give a report of the speed of each individual test. See
+more details on other options for running the suite below.
+
+A macro test suite (with full traces and more intensive benchmarks) is
+also available; for this, see http://cgit.freedesktop.org/cairo-traces.
+The macro-benchmarks are better measures of actual real-world
+performance, and should be preferred over the micro-benchmarks (and over
+make perf) for identifying performance regressions or improvements. If
+you copy or symlink this repository at cairo/perf/cairo-traces, then
+make perf will run those tests as well.
+
+Running the micro-benchmarks
+----------------------------
+The micro-benchmark performance suite is composed of a series of
+hand-written, short, synthetic tests that measure the speed of doing a
+simple operation such as painting a surface or showing glyphs. These aim
+to give very good feedback on whether a performance related patch is
+successful without causing any performance degradations elsewhere.
+
+The micro-benchmarks are compiled into a single executable called
+cairo-perf-micro, which is what "make perf" executes. Some
+examples of running it:
+
+ # Report on all tests with default number of iterations:
+ ./cairo-perf-micro
+
+ # Report on 100 iterations of all gradient tests:
+ ./cairo-perf-micro -i 100 gradient
+
+ # Generate raw results for 10 iterations into cairo.perf
+ ./cairo-perf-micro -r -i 10 > cairo.perf
+ # Append 10 more iterations of the paint test
+ ./cairo-perf-micro -r -i 10 paint >> cairo.perf
+
+Raw results aren't useful for reading directly, but are quite useful
+when using cairo-perf-diff to compare separate runs (see more
+below). The advantage of using the raw mode is that test runs can be
+generated incrementally and appended to existing reports.
+
+Generating comparisons of separate runs
+---------------------------------------
+It's often useful to generate a chart showing the comparison of two
+separate runs of the cairo performance suite, (for example, after
+applying a patch intended to improve cairo's performance). The
+cairo-perf-diff script can be used to compare two report files
+generated by cairo-perf.
+
+Again, by way of example:
+
+ # Show performance changes from cairo-orig.perf to cairo-patched.perf
+ ./cairo-perf-diff cairo-orig.perf cairo-patched.perf
+
+This will work whether the data files were generate in raw mode (with
+cairo-perf -r) or cooked, (cairo-perf without -r).
+
+Finally, in its most powerful mode, cairo-perf-diff accepts two git
+revisions and will do all the work of checking each revision out,
+building it, running cairo-perf for each revision, and finally
+generating the report. Obviously, this mode only works if you are
+using cairo within a git repository, (and not from a tar file). Using
+this mode is as simple as passing the git revisions to be compared to
+cairo-perf-diff:
+
+ # Compare cairo 1.2.6 to cairo 1.4.0
+ ./cairo-perf-diff 1.2.6 1.4.0
+
+ # Measure the impact of the latest commit
+ ./cairo-perf-diff HEAD~1 HEAD
+
+As a convenience, this common desire to measure a single commit is
+supported by passing a single revision to cairo-perf-diff, in which
+case it will compare it to the immediately preceding commit. So for
+example:
+
+ # Measure the impact of the latest commit
+ ./cairo-perf-diff HEAD
+
+ # Measure the impact of an arbitrary commit by SHA-1
+ ./cairo-perf-diff aa883123d2af90
+
+Also, when passing git revisions to cairo-perf-diff like this, it will
+automatically cache results and re-use them rather than re-running
+cairo-perf over and over on the same versions. This means that if you
+ask for a report that you've generated in the past, cairo-perf-diff
+should return it immediately.
+
+Now, sometimes it is desirable to generate more iterations rather than
+re-using cached results. In this case, the -f flag can be used to
+force cairo-perf-diff to generate additional results in addition to
+what has been cached:
+
+ # Measure the impact of latest commit (force more measurement)
+ ./cairo-perf-diff -f
+
+And finally, the -f mode is most useful in conjunction with the --
+option to cairo-perf-diff which allows you to pass options to the
+underlying cairo-perf runs. This allows you to restrict the additional
+test runs to a limited subset of the tests.
+
+For example, a frequently used trick is to first generate a chart with
+a very small number of iterations for all tests:
+
+ ./cairo-perf-diff HEAD
+
+Then, if any of the results look suspicious, (say there's a slowdown
+reported in the text tests, but you think the text test shouldn't be
+affected), then you can force more iterations to be tested for only
+those tests:
+
+ ./cairo-perf-diff -f HEAD -- text
+
+Generating comparisons of different backends
+--------------------------------------------
+An alternate question that is often asked is, "how does the speed of one
+backend compare to another?". cairo-perf-compare-backends can read files
+generated by cairo-perf and produces a comparison of the backends for every
+test.
+
+Again, by way of example:
+
+ # Show relative performance of the backends
+ ./cairo-perf-compare-backends cairo.perf
+
+This will work whether the data files were generate in raw mode (with
+cairo-perf -r) or cooked, (cairo-perf without -r).
+
+
+Creating a new performance test
+-------------------------------
+This is where we could use everybody's help. If you have encountered a
+sequence of cairo operations that are slower than you would like, then
+please provide a performance test. Writing a test is very simple, it
+requires you to write only a small C file with a couple of functions,
+one of which exercises the cairo calls of interest.
+
+Here is the basic structure of a performance test file:
+
+ /* Copyright © 2006 Kind Cairo User
+ *
+ * ... Licensing information here ...
+ * Please copy the MIT blurb as in other tests
+ */
+
+ #include "cairo-perf.h"
+
+ static cairo_time_t
+ do_my_new_test (cairo_t *cr, int width, int height)
+ {
+ cairo_perf_timer_start ();
+
+ /* Make the cairo calls to be measured */
+
+ cairo_perf_timer_stop ();
+
+ return cairo_perf_timer_elapsed ();
+ }
+
+ void
+ my_new_test (cairo_perf_t *perf, cairo_t *cr, int width, int height)
+ {
+ /* First do any setup for which the execution time should not
+ * be measured. For example, this might include loading
+ * images from disk, creating patterns, etc. */
+
+ /* Then launch the actual performance testing. */
+ cairo_perf_run (perf, "my_new_test", do_my_new_test);
+
+ /* Finally, perform any cleanup from the setup above. */
+ }
+
+That's really all there is to writing a new test. The first function
+above is the one that does the real work and returns a timing
+number. The second function is the one that will be called by the
+performance test rig (see below for how to accomplish that), and
+allows for multiple performance cases to be written in one file,
+(simply call cairo_perf_run once for each case, passing the
+appropriate callback function to each).
+
+We go through this dance of indirectly calling your own function
+through cairo_perf_run so that cairo_perf_run can call your function
+many times and measure statistical properties over the many runs.
+
+Finally, to fully integrate your new test case you just need to add
+your new test to three different lists. (TODO: We should set this up
+better so that the lists are maintained automatically---computed from
+the list of files in cairo/perf, for example). Here's what needs to be
+added:
+
+ 1. Makefile.am: Add the new file name to the cairo_perf_SOURCES list
+
+ 2. cairo-perf.h: Add a new CAIRO_PERF_DECL line with the name of your
+ function, (my_new_test in the example above)
+
+ 3. cairo-perf-micro.c: Add a new row to the list at the end of the
+ file. A typical entry would look like:
+
+ { my_new_test, 16, 64 }
+
+ The last two numbers are a minimum and a maximum image size at
+ which your test should be exercised. If these values are the same,
+ then only that size will be used. If they are different, then
+ intermediate sizes will be used by doubling. So in the example
+ above, three tests would be performed at sizes of 16x16, 32x32 and
+ 64x64.
+
+
+How to run cairo-perf-diff on WINDOWS
+-------------------------------------
+This section explains the specifics of running cairo-perf-diff under
+win32 plateforms. It assumes that you have installed a UNIX-like shell
+environment such as MSYS (distributed as part of MinGW).
+
+ 1. From your Mingw32 window, be sure to have all of your MSVC environ-
+ ment variables set up for proper compilation using 'make'
+
+ 2. Add the %GitBaseDir%/Git/bin path to your environment, replacing the
+ %GitBaseDir% by whatever directory your Git version is installed to.
+
+ 3. Comment out the "UNSET CDPATH" line in the git-sh-setup script
+ (located inside the ...Git/bin directory) by putting a "#" at the
+ beginning of the line.
+
+you should be ready to go !
+
+From your mingw32 window, go to your cairo/perf directory and run the
+cairo-perf-diff script with the right arguments.
+
+Thanks for your contributions and have fun with cairo!
+
+TODO
+----
+Add a control language for crafting and running small sets of micro
+benchmarks.

+Usage:
+For comparing files created my cairo-perf:
+
+ $argv0 old.perf new.perf
+
+For comparing (cached) performance of revisions:
+
+ $argv0 [OPTIONS] <revision> [-- cairo-perf options]
+ $argv0 [OPTIONS] <rev1> <rev2> [-- cairo-perf-options]
+
+If given a single revision, compares its results to that of its
+(first-parent) predecessor. Otherwise compares the two given revisions.
+The revisions can be any revision accepted by git. For example:
+
+ $argv0 HEAD # Show impact of latest commit
+ $argv0 1.2.0 1.2.4 # Compare performance of 1.2.0 to 1.2.4
+
+Options:
+
+-f, --force
+ Forces cairo-perf-diff to re-run performance tests
+ even if cached performance data is available.
+
+-h, --html
+ With this option performance changes are summarized
+ as HTML table.
+
+-t, --trace
+ Compare performance using trace replays instead of
+ microbenchmarks.
+
+Additional options can be passed the child cairo-perf process
+by separating them with a double hyphen (--). For example, to
+examine what the impact of the latest change is on the stroke
+test you might use:
+
+ $argv0 HEAD -- stroke
+
+The performance results are cached in .perf next to the .git directory.
+
+Set CAIRO_AUTOGEN_OPTIONS to pass options to autogen for both
+builds.

+Usage:
+As opposed to its sibling, cairo-perf-diff, cairo-perf-graph targets
+reviewing changes between series by graphically comparing the performance
+at each commit.
+
+The two revisions can be any revision accepted by git. For example:
+
+ $argv0 1.2.0 1.2.4 # Compare performance of 1.2.0 to 1.2.4
+
+Options:
+
+-f, --force
+ Forces cairo-perf-diff to re-run performance tests
+ even if cached performance data is available.
+
+-h, --html
+ With this option performance changes are summarized
+ as HTML table.
+
+Additional options can be passed the child cairo-perf process
+by separating them with a double hyphen (--). For example, to
+examine what the impact of the latest change is on the stroke
+test you might use:
+
+ $argv0 HEAD -- stroke
+
+The performance results are cached in .perf next to the .git directory.
+
+Set CAIRO_AUTOGEN_OPTIONS to pass options to autogen for both
+builds.

- * We need to compare the x-coordinates of a pair of lines for a particular y,
- * without loss of precision.
- *
- * The x-coordinate along an edge for a given y is:
- * X = A_x + (Y - A_y) * A_dx / A_dy
- *
- * So the inequality we wish to test is:
- * A_x + (Y - A_y) * A_dx / A_dy ∘ B_x + (Y - B_y) * B_dx / B_dy,
- * where ∘ is our inequality operator.
- *
- * By construction, we know that A_dy and B_dy (and (Y - A_y), (Y - B_y)) are
- * all positive, so we can rearrange it thus without causing a sign change:
- * A_dy * B_dy * (A_x - B_x) ∘ (Y - B_y) * B_dx * A_dy
- * - (Y - A_y) * A_dx * B_dy
- *
- * Given the assumption that all the deltas fit within 32 bits, we can compute
- * this comparison directly using 128 bit arithmetic. For certain, but common,
- * input we can reduce this down to a single 32 bit compare by inspecting the
- * deltas.
- *
- * (And put the burden of the work on developing fast 128 bit ops, which are
- * required throughout the tessellator.)
- *

+Regression test suite for cairo.
+
+How to use cairo's test suite
+=============================
+Using this test should be as simple as running:
+
+ make test
+
+assuming that the cairo distribution in the directory above has been
+configured and built. The test suite here goes through some effort to
+run against the locally compiled library rather than any installed
+version, but those efforts may fall short depending on the level of your
+libtool madness.
+
+The results of the test suite run are summarized in an index.html
+file, which, when viewed in a web browser makes it quite easy to
+visually see any failed renderings alongside the corresponding
+reference image, (and a diff image as well).
+
+The test suite needs to be run before any code is committed and before
+any release. See below for hints and rules governing the use of the suite.
+
+The test suite is built as a single binary, which allows you to choose
+individual or categories of tests to run. For example, if you want to
+run all text related tests you can use:
+ ./cairo-test-suite text
+Or if you want to check the current status of known failures:
+ ./cairo-test-suite XFAIL
+Or to run a subset of tests, use the -k option to run only the tests
+that include the given keyword:
+ ./cairo-test-suite -k downscale
+The binary also permits controlling which backend is used via the
+CAIRO_TEST_TARGET environment variable, so for instance:
+ CAIRO_TEST_TARGET=gl ./cairo-test-suite -k blur
+This binary should be backwards-compatible with all library versions,
+allowing you to compare current versus past behaviour for any test.
+
+Tailoring tests running
+-----------------------
+There are some mechanisms to limit the tests run during "make test".
+These come very handy when doing development, but should not be used
+to circumvent the "pass" requirements listed below.
+
+make's TARGETS environment variable can be used to limit the backends when
+running the tests. It should contain a (space-, comma-separated) list of
+backends. CAIRO_TESTS environment variable, which is a comma-, space-seperated
+lists, can be used to limit the tests run.
+For example:
+
+ CAIRO_TESTS="zero-alpha" make test TARGETS=image,ps
+
+make's FORMAT variable can also be used to limit the content formats when
+running the tests. It should contain a (space-, comma-separated) list of
+content formats to test.
+For example:
+
+ CAIRO_TESTS="zero-alpha" make test TARGETS=image,ps FORMAT="rgb,rgba"
+
+Another very handy mechanism when trying to fix bugs is:
+
+ make retest
+
+This will re-run the test suite, but only on tests that failed on the
+last run. So this is a much faster way of checking if changes actually
+fix bugs rather than running the entire test suite again.
+
+The test suite first compares the output from the current run against the
+previous in order to skip more expensive image comparisons . If you think
+this is interfering with the results, you can clear the cached results using:
+
+ make clean-caches
+
+Running tests under modified environments or tools
+-------------------------------------------------
+To run tests under a tool like gdb, one can use the run target and
+the TOOL variable. For example:
+
+ CAIRO_TESTS=user-font make run TOOL=gdb TARGETS=pdf
+
+If you want to run under valgrind, there is a specific target for that
+that also sets a bunch of useful valgrind options. Try:
+
+ CAIRO_TESTS=user-font make check-valgrind
+
+You can run tests under a modified environment you can use the ENV
+make variable. However, that environment will also affect the libtool
+wrapper of the tests. To only affect the actual test binaries, pass
+such environment as TOOL:
+
+ CAIRO_TESTS=user-font make run TOOL="LD_PRELOAD=/path/to/something.so"
+
+Getting the elusive zero failures
+---------------------------------
+It's generally been very difficult to achieve a test run with zero
+failures. The difficulties stem from the various versions of the many
+libraries that the test suite depends on, (it depends on a lot more
+than cairo itself), as well as fonts and other system-specific
+settings. If your system differs significantly from the system on
+which the reference images were generated, then you will likely see
+the test suite reporting "failures", (even if cairo is working just
+fine).
+
+We are constantly working to reduce the number of variables that need
+to be tweaked to get a clean run, (for example, by bundling fonts with
+the test suite itself), and also working to more carefully document
+the software configuration used to generate the reference images.
+
+Here are some of the relevant details:
+
+ * Your system must have a copy of the DejaVu font, the sha1sum of
+ the version used are listed in [...]. These are
+ "DejaVu Sans" (DejaVuSans.ttf) [1cd336329f45f241002ded61893d91e3acd04436];
+ "DejaVu Sans Mono" (DejaVuSansMono.ttf) [0458c0f0fb57f3eb8ced62f26fe7c5ed4e6a9a68];
+ "DejaVu Serif" (DejaVuSerif.ttf) [93502d0d0445d1fe1c9f51e51b3e0169266346ce];
+ [the DejaVu fonts can be installed from the ttf-dejavu 2.33-2 Debian package]
+ and also
+ "Nimbus Sans L" (n019003l.pfb)
+ [which can be found in the gsfonts Debian package].
+
+ * Currently, you must be using a build of cairo using freetype
+ (cairo-ft) as the default font backend. Otherwise all tests
+ involving text are likely to fail.
+
+ * To test the pdf backend, you will want the very latest version of
+ poppler as made available via git:
+
+ git clone git://anongit.freedesktop.org/git/poppler/poppler
+
+ As of this writing, no released version of poppler contains all
+ the fixes you will need to avoid false negatives from the test
+ suite.
+
+ * To test the ps backend, you will need ghostscript version 9.04.
+
+ * Testing the xlib backend is problematic since many X server
+ drivers have bugs that are exercised by the test suite. (Or, if
+ not actual bugs, differ slightly in their output in such a way
+ that the test suite will report errors.) This can be quite handy
+ if you want to debug an X server driver, but since most people
+ don't want to do that, another option is to run against a headless
+ X server that uses only software for all rendering. One such X
+ server is Xvfb which can be started like this:
+
+ Xvfb -screen 0 1680x1024x24 -ac -nolisten tcp :2
+
+ after which the test suite can be run against it like so:
+
+ DISPLAY=:2 make test
+
+ We have been using Xvfb for testing cairo releases and ensuring
+ that all tests behave as expected with this X server.
+
+What if I can't make my system match?
+-------------------------------------
+For one reason or another, you may be unable to get a clean run of the
+test suite even if cairo is working properly, (for example, you might
+be on a system without freetype). In this case, it's still useful to
+be able to determine if code changes you make to cairo result in any
+regressions to the test suite. But it's hard to notice regressions if
+there are many failures both before and after your changes.
+
+For this scenario, you can capture the output of a run of the test
+suite before your changes, and then use the CAIRO_REF_DIR environment
+variable to use that output as the reference images for a run after
+your changes. The process looks like this:
+
+ # Before code change there may be failures we don't care about
+ make test
+
+ # Let's save those output images
+ mkdir /some/directory/
+ cp -r test/output /some/directory/
+
+ # hack, hack, hack
+
+ # Now to see if nothing changed:
+ CAIRO_REF_DIR=/some/directory/ make test
+
+Best practices for cairo developers
+===================================
+If we all follow the guidelines below, then both the test suite and
+cairo itself will stay much healthier, and we'll all have a lot more
+fun hacking on cairo.
+
+Before committing
+-----------------
+All tests should return a result of PASS or XFAIL. The XFAIL results
+indicate known bugs. The final message should be one of the following:
+
+ All XX tests behaved as expected (YY expected failures)
+ All XX tests passed
+
+If any tests have a status of FAIL, then the new code has caused a
+regression error which should be fixed before the code is committed.
+
+When a new bug is found
+-----------------------
+A new test case should be added by imitating the style of an existing
+test. This means adding the following files:
+
+ new-bug.c
+ reference/new-bug.ref.png
+ reference/new-bug.xfail.png
+
+Where new-bug.c is a minimal program to demonstrate the bug, following
+the style of existing tests. The new-bug.ref.png image should contain
+the desired result of new-bug.c if the bug were fixed while
+new-bug.xfail.png contains the current results of the test.
+
+Makefile.sources should be edited by adding new-bug.c to test_sources.
+And last but not least, don't forget to "git add" the new files.
+
+When a new feature is added
+---------------------------
+It's important for the regression suite to keep pace with development
+of the library. So a new test should be added for each new feature.
+The work involved is similar the work described above for new bugs.
+The only distinction is that the test is expected to pass so it
+should not need a new-bug.xfail.png file.
+
+While working on a test
+-----------------------
+Before a bugfix or feature is ready, it may be useful to compare
+output from different builds. For convenience, you can set
+CAIRO_REF_DIR to point at a previous test directory, relative
+to the current test directory, and any previous output will be
+used by preference as reference images.
+
+When a bug is fixed
+-------------------
+The fix should be verified by running the test suite which should
+result in an "unexpected pass" for the test of interest. Rejoice as
+appropriate, then remove the relevant xfail.png file from git.
+
+Before releasing
+----------------
+All tests should return a result of PASS for all supported (those enabled by
+default) backends, meaning all known bugs are fixed, resulting in the happy
+message:
+
+ All XX tests passed
+
+Some notes on limitations in poppler
+====================================
+One of the difficulties of our current test infrastructure is that we
+rely on external tools to convert cairo's vector output (PDF,
+PostScript, and SVG), into an image that can be used for the image
+comparison. This means that any bugs in that conversion tool will
+result in false negatives in the test suite.
+
+We've identified several such bugs in the poppler library which is
+used to convert PDF to an image. This is particularly discouraging
+because 1) poppler is free software that will be used by *many* cairo
+users, and 2) poppler calls into cairo for its rendering so it should
+be able to do a 100% faithful conversion.
+
+So we have an interest in ensuring that these poppler bugs get fixed
+sooner rather than later. As such, we're trying to be good citizens by
+reporting all such poppler bugs that we identify to the poppler
+bugzilla. Here's a tracking bug explaining the situation:
+
+ Poppler does not yet handle everything in the cairo test suite
+ https://bugs.freedesktop.org/show_bug.cgi?id=12143
+
+Here's the rule: If a cairo-pdf test reports a failure, but viewing
+the resulting PDF file with acroread suggests that the PDF itself is
+correct, then there's likely a bug in poppler. In this case, we can
+simply report the poppler bug, (making it block 12143 above), post the
+PDF result from the test suite, and list the bug in this file. Once
+we've done this, we can capture poppler's buggy output as a
+pdf-specific reference image (as reference/*.xfail.png) so that the
+test suite will regard the test as passing, (and we'll ensure there
+is no regression).
+
+Once the poppler bug gets fixed, the test suite will start reporting a
+false negative again, and this will be easy to fix by simply removing
+the pdf-specific reference image.
+
+Here are the reported poppler bugs and the tests they affect:
+
+Poppler doesn't correctly handle gradients with transparency

+/*
+ * WHAT THIS TEST DOES
+ *
+ * This test tests that for all public APIs Cairo behaves correct, consistent
+ * and most of all doesn't crash. It does this by calling all APIs that take
+ * surfaces or contexts and calling them on specially prepared arguments that
+ * should fail when called on this function.
+ *
+ * ADDING NEW FUNCTIONS
+ *
+ * You need (for adding the function cairo_surface_foo):
+ * 1) A surface_test_func_t named test_cairo_surface_foo that gets passed the
+ * prepared surface and has the job of calling the function and checking
+ * the return value (if one exists) for correctness. The top of this file
+ * contains all these shim functions.
+ * 2) Knowledge if the function behaves like a setter or like a getter. A
+ * setter should set an error status on the surface, a getter does not
+ * modify the function.
+ * 3) Knowledge if the function only works for a specific surface type and for
+ * which one.
+ * 4) An entry in the tests array using the TEST() macro. It takes as arguments:
+ * - The function name
+ * - TRUE if the function modifies the surface, FALSE otherwise
+ * - the surface type for which the function is valid or -1 if it is valid
+ * for all surface types.
+ *
+ * FIXING FAILURES
+ *
+ * The test will dump failures notices into the api-special-cases.log file (when
+ * it doesn't crash). These should be pretty self-explanatory. Usually it is
+ * enough to just add a new check to the function it complained about.

+/* This test was originally written to exercise a bug in pixman in
+ * which it would scribble all over memory when given a particular
+ * (and bogus) trapezoid. However, a recent change to
+ * _cairo_fixed_from_double changed the details of the bogus trapezoid
+ * (it overflows in a different way now), so the bug is being masked.
+ *
+ * According to Vladimir, (http://lists.freedesktop.org/archives/cairo/2006-November/008482.html):
+ *
+ * Before the change, the two trapezoids that were generated were:
+ *
+ * Trap[0]: T: 0x80000000 B: 0x80000003
+ * L: [(0x000a0000, 0x80000000) (0x00080000, 0x00080000)]
+ * R: [(0x01360000, 0x80000000) (0x01380000, 0x00080000)]
+ * Trap[1]: T: 0x80000003 B: 0x00080000
+ * L: [(0x000a0000, 0x80000000) (0x00080000, 0x00080000)]
+ * R: [(0x01360000, 0x80000000) (0x01380000, 0x00080000)]
+ *
+ * After the change, the L/R coordinates are identical for both traps, but
+ * the top and bottom change:
+ *
+ * Trap[0]: t: 0x80000000 b: 0xfda80003
+ * l: [(0x000a0000, 0x80000000) (0x00080000, 0x00080000)]
+ * r: [(0x01360000, 0x80000000) (0x01380000, 0x00080000)]
+ * Trap[1]: t: 0xfda80003 b: 0x00080000
+ * l: [(0x000a0000, 0x80000000) (0x00080000, 0x00080000)]
+ * r: [(0x01360000, 0x80000000) (0x01380000, 0x00080000)]
+ *
+ * I think the fix we want here is to rewrite this test to call
+ * directly into pixman with the trapezoid of interest, (which will
+ * require adding a new way to configure cairo for "testing" which
+ * will prevent the hiding of internal library symbols.

+/* Exercises a case of seam appearing between two polygons in the image
+ * backend but not in xlib [using pixman].
+ *
+ * The test case draws two abutting quads both individually on the
+ * leftm combining them with operator ADD, and in one go on the right.
+ * Both methods should show no signs of seaming at the common edge
+ * between the two quads, but the individually drawn ones have a
+ * slight seam.
+ *
+ * The cause of the seam is that there are slight differences in the
+ * output of the analytical coverage rasterization and the
+ * supersampling rasterization methods, both employed by
+ * cairo-tor-scan-converter. When drawn individually, the scan

+ *
+ * 2004-10-27 Carl Worth <cworth@cworth.org>
+ *
+ * There's currently a regression bug in the tessellation code. This
+ * causes each of these simple star shapes to be filled incorrectly.
+ *
+ * It looks like right now we can get this test to pass by doing:
+ *
+ * cvs update -r 1.16 src/cairo_traps.c
+ *
+ * But we don't want to revert that change permanently since it
+ * really does correct some bugs. It must be that the old version of
+ * the code is masking some other bugs in the tessellation code. My
+ * current plan is to back this revision up for the next snapshot,
+ * but not to list the test as an expected failure since I'm
+ * planning on doing the new tessellator which should fix this
+ * problem.
+ *
+ * 2005-01-11 Carl Worth <cworth@cworth.org>
+ *
+ * Keith committed some fixes that fix the original size-20
+ * star_path:
+ *
+ * * src/cairo_wideint.c: (_cairo_int32x32_64_mul),
+ * (_cairo_int64x64_128_mul):
+ * * src/cairo_wideint.h:
+ * int32x32_64_mul and int64x64_128_mul are different from their
+ * unsigned compatriots
+ *
+ * 2005-01-12 Carl Worth <cworth@cworth.org>

+ * Going back to the SVG test suite, however, the original star
+ * shape is still broken. Adding both shapes now as little_star_path
+ * and big_star_path.

+ * 2006-06-22 Carl Worth <cworth@cworth.org>
+ *
+ * This is a test case to demonstrate the following bug in the xlib backend:
+ *
+ * Some characters aren't displayed when using xlib (cache usage missing freeze/thaw)
+ * https://bugs.freedesktop.org/show_bug.cgi?id=6955
+ *
+ * We replicate this bug by using the cairo_scaled_font_set_max_glyphs_per_font
+ * function to artificially induce cache pressure. (This function was added
+ * for this very purpose.)
+ *
+ * 2006-06-22 Carl Worth <cworth@cworth.org>
+ *
+ * Bug was simple enough to solve by just adding a freeze/thaw pair
+ * around the scaled_font's glyph cache in
+ * _cairo_xlib_surface_show_glyphs, (I went ahead and added
+ * _cairo_sacled_font_freeze/thaw_cache functions for this).

+ *
+ * Bug reported:
+ *
+ * From: Chris <fltk@functionalfuture.com>
+ * Subject: [cairo] Render to image buffer artifacts
+ * To: cairo@cairographics.org
+ * Date: Fri, 07 Jan 2005 02:22:28 -0500
+ *
+ * I've attached the code and image that shows this off. Scaling at
+ * different levels seems to change the corruption.
+ *
+ * For some reason there are artifacts in the alpha channel. I don't know
+ * if that's the only place, but the alpha channel looks bad.
+ *
+ * If you run the code and parse the attached image, directing stdout to a
+ * file, you can see in the lower left corner there are alpha values where
+ * it should be transparent.
+ * [...]
+ *
+ * 2005-01-11 Carl Worth <cworth@cworth.org>
+ *
+ * I trimmed the original test case down to the code that appears here.

+ *
+ * It looks like cairo_show_surface has no effect if it follows a

+ *
+ * 2005-04-02 Carl Worth <cworth@cworth.org>
+ *
+ * Status: RESOLVED
+ *
+ * Inside cairo_show_surface the current point was being used as
+ * both source and destination offsets. After fixing that to use 0,0
+ * as the source offset and the current point as the destination
+ * offset, the bug seems to be gone.

+
+Build Instructions
+1. Download cross platform make from http://www.cmake.org
+2. Download libtiff from http://www.libtiff.org. Download libpng from http://www.libpng.org
+3. Edit CMakeLists.txt to tell it where to find your tiff library
+4. Type cmake .
+5. Type make . (or on Windows systems cmake makes a Visual Studio
+Project file)
+6. To specify the install directory, use make install DESTDIR="/home/me/mydist"
+
+Usage
+
+pdiff image1.(tif | png) image2.(tif | png) [options]
+-verbose : Turns on verbose mode
+-fov deg: field of view, deg, in degrees. Usually between 10.0 to 85.0.
+This controls how much of the screen the oberserver is seeing. Front row of
+a theatre has a field of view of around 25 degrees. Back row has a field of
+ view of around 60 degrees.
+-threshold p : Sets the number of pixels, p, to reject. For example if p is
+ 100, then the test fails if 100 or more pixels are perceptably different.
+-gamma g : The gamma to use to convert to RGB linear space. Default is 2.2
+-luminance l: The luminance of the display the observer is seeing. Default
+ is 100 candela per meter squared

+ GNU GENERAL PUBLIC LICENSE
+ Version 2, June 1991
+
+ Copyright (C) 1989, 1991 Free Software Foundation, Inc.
+ 51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA
+ Everyone is permitted to copy and distribute verbatim copies
+ of this license document, but changing it is not allowed.
+
+ Preamble
+
+ The licenses for most software are designed to take away your
+freedom to share and change it. By contrast, the GNU General Public
+License is intended to guarantee your freedom to share and change free
+software--to make sure the software is free for all its users. This
+General Public License applies to most of the Free Software
+Foundation's software and to any other program whose authors commit to
+using it. (Some other Free Software Foundation software is covered by
+the GNU Lesser General Public License instead.) You can apply it to
+your programs, too.
+
+ When we speak of free software, we are referring to freedom, not
+price. Our General Public Licenses are designed to make sure that you
+have the freedom to distribute copies of free software (and charge for
+this service if you wish), that you receive source code or can get it
+if you want it, that you can change the software or use pieces of it
+in new free programs; and that you know you can do these things.
+
+ To protect your rights, we need to make restrictions that forbid
+anyone to deny you these rights or to ask you to surrender the rights.
+These restrictions translate to certain responsibilities for you if you
+distribute copies of the software, or if you modify it.
+
+ For example, if you distribute copies of such a program, whether
+gratis or for a fee, you must give the recipients all the rights that
+you have. You must make sure that they, too, receive or can get the
+source code. And you must show them these terms so they know their
+rights.
+
+ We protect your rights with two steps: (1) copyright the software, and
+(2) offer you this license which gives you legal permission to copy,
+distribute and/or modify the software.
+
+ Also, for each author's protection and ours, we want to make certain
+that everyone understands that there is no warranty for this free
+software. If the software is modified by someone else and passed on, we
+want its recipients to know that what they have is not the original, so
+that any problems introduced by others will not reflect on the original
+authors' reputations.
+
+ Finally, any free program is threatened constantly by software
+patents. We wish to avoid the danger that redistributors of a free
+program will individually obtain patent licenses, in effect making the
+program proprietary. To prevent this, we have made it clear that any
+patent must be licensed for everyone's free use or not licensed at all.
+
+ The precise terms and conditions for copying, distribution and
+modification follow.
+
+ GNU GENERAL PUBLIC LICENSE
+ TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
+
+ 0. This License applies to any program or other work which contains
+a notice placed by the copyright holder saying it may be distributed
+under the terms of this General Public License. The "Program", below,
+refers to any such program or work, and a "work based on the Program"
+means either the Program or any derivative work under copyright law:
+that is to say, a work containing the Program or a portion of it,
+either verbatim or with modifications and/or translated into another
+language. (Hereinafter, translation is included without limitation in
+the term "modification".) Each licensee is addressed as "you".
+
+Activities other than copying, distribution and modification are not
+covered by this License; they are outside its scope. The act of
+running the Program is not restricted, and the output from the Program
+is covered only if its contents constitute a work based on the
+Program (independent of having been made by running the Program).
+Whether that is true depends on what the Program does.
+
+ 1. You may copy and distribute verbatim copies of the Program's
+source code as you receive it, in any medium, provided that you
+conspicuously and appropriately publish on each copy an appropriate
+copyright notice and disclaimer of warranty; keep intact all the
+notices that refer to this License and to the absence of any warranty;
+and give any other recipients of the Program a copy of this License
+along with the Program.
+
+You may charge a fee for the physical act of transferring a copy, and
+you may at your option offer warranty protection in exchange for a fee.
+
+ 2. You may modify your copy or copies of the Program or any portion
+of it, thus forming a work based on the Program, and copy and
+distribute such modifications or work under the terms of Section 1
+above, provided that you also meet all of these conditions:
+
+ a) You must cause the modified files to carry prominent notices
+ stating that you changed the files and the date of any change.
+
+ b) You must cause any work that you distribute or publish, that in
+ whole or in part contains or is derived from the Program or any
+ part thereof, to be licensed as a whole at no charge to all third
+ parties under the terms of this License.
+
+ c) If the modified program normally reads commands interactively
+ when run, you must cause it, when started running for such
+ interactive use in the most ordinary way, to print or display an
+ announcement including an appropriate copyright notice and a
+ notice that there is no warranty (or else, saying that you provide
+ a warranty) and that users may redistribute the program under
+ these conditions, and telling the user how to view a copy of this
+ License. (Exception: if the Program itself is interactive but
+ does not normally print such an announcement, your work based on
+ the Program is not required to print an announcement.)
+
+These requirements apply to the modified work as a whole. If
+identifiable sections of that work are not derived from the Program,
+and can be reasonably considered independent and separate works in
+themselves, then this License, and its terms, do not apply to those
+sections when you distribute them as separate works. But when you
+distribute the same sections as part of a whole which is a work based
+on the Program, the distribution of the whole must be on the terms of
+this License, whose permissions for other licensees extend to the
+entire whole, and thus to each and every part regardless of who wrote it.
+
+Thus, it is not the intent of this section to claim rights or contest
+your rights to work written entirely by you; rather, the intent is to
+exercise the right to control the distribution of derivative or
+collective works based on the Program.
+
+In addition, mere aggregation of another work not based on the Program
+with the Program (or with a work based on the Program) on a volume of
+a storage or distribution medium does not bring the other work under
+the scope of this License.
+
+ 3. You may copy and distribute the Program (or a work based on it,
+under Section 2) in object code or executable form under the terms of
+Sections 1 and 2 above provided that you also do one of the following:
+
+ a) Accompany it with the complete corresponding machine-readable
+ source code, which must be distributed under the terms of Sections
+ 1 and 2 above on a medium customarily used for software interchange; or,
+
+ b) Accompany it with a written offer, valid for at least three
+ years, to give any third party, for a charge no more than your
+ cost of physically performing source distribution, a complete
+ machine-readable copy of the corresponding source code, to be
+ distributed under the terms of Sections 1 and 2 above on a medium
+ customarily used for software interchange; or,
+
+ c) Accompany it with the information you received as to the offer
+ to distribute corresponding source code. (This alternative is
+ allowed only for noncommercial distribution and only if you
+ received the program in object code or executable form with such
+ an offer, in accord with Subsection b above.)
+
+The source code for a work means the preferred form of the work for
+making modifications to it. For an executable work, complete source
+code means all the source code for all modules it contains, plus any
+associated interface definition files, plus the scripts used to
+control compilation and installation of the executable. However, as a
+special exception, the source code distributed need not include
+anything that is normally distributed (in either source or binary
+form) with the major components (compiler, kernel, and so on) of the
+operating system on which the executable runs, unless that component
+itself accompanies the executable.
+
+If distribution of executable or object code is made by offering
+access to copy from a designated place, then offering equivalent
+access to copy the source code from the same place counts as
+distribution of the source code, even though third parties are not
+compelled to copy the source along with the object code.
+
+ 4. You may not copy, modify, sublicense, or distribute the Program
+except as expressly provided under this License. Any attempt
+otherwise to copy, modify, sublicense or distribute the Program is
+void, and will automatically terminate your rights under this License.
+However, parties who have received copies, or rights, from you under
+this License will not have their licenses terminated so long as such
+parties remain in full compliance.
+
+ 5. You are not required to accept this License, since you have not
+signed it. However, nothing else grants you permission to modify or
+distribute the Program or its derivative works. These actions are
+prohibited by law if you do not accept this License. Therefore, by
+modifying or distributing the Program (or any work based on the
+Program), you indicate your acceptance of this License to do so, and
+all its terms and conditions for copying, distributing or modifying
+the Program or works based on it.
+
+ 6. Each time you redistribute the Program (or any work based on the
+Program), the recipient automatically receives a license from the
+original licensor to copy, distribute or modify the Program subject to
+these terms and conditions. You may not impose any further
+restrictions on the recipients' exercise of the rights granted herein.
+You are not responsible for enforcing compliance by third parties to
+this License.
+
+ 7. If, as a consequence of a court judgment or allegation of patent
+infringement or for any other reason (not limited to patent issues),
+conditions are imposed on you (whether by court order, agreement or
+otherwise) that contradict the conditions of this License, they do not
+excuse you from the conditions of this License. If you cannot
+distribute so as to satisfy simultaneously your obligations under this
+License and any other pertinent obligations, then as a consequence you
+may not distribute the Program at all. For example, if a patent
+license would not permit royalty-free redistribution of the Program by
+all those who receive copies directly or indirectly through you, then
+the only way you could satisfy both it and this License would be to
+refrain entirely from distribution of the Program.
+
+If any portion of this section is held invalid or unenforceable under
+any particular circumstance, the balance of the section is intended to
+apply and the section as a whole is intended to apply in other
+circumstances.
+
+It is not the purpose of this section to induce you to infringe any
+patents or other property right claims or to contest validity of any
+such claims; this section has the sole purpose of protecting the
+integrity of the free software distribution system, which is
+implemented by public license practices. Many people have made
+generous contributions to the wide range of software distributed
+through that system in reliance on consistent application of that
+system; it is up to the author/donor to decide if he or she is willing
+to distribute software through any other system and a licensee cannot
+impose that choice.
+
+This section is intended to make thoroughly clear what is believed to
+be a consequence of the rest of this License.
+
+ 8. If the distribution and/or use of the Program is restricted in
+certain countries either by patents or by copyrighted interfaces, the
+original copyright holder who places the Program under this License
+may add an explicit geographical distribution limitation excluding
+those countries, so that distribution is permitted only in or among
+countries not thus excluded. In such case, this License incorporates
+the limitation as if written in the body of this License.
+
+ 9. The Free Software Foundation may publish revised and/or new versions
+of the General Public License from time to time. Such new versions will
+be similar in spirit to the present version, but may differ in detail to
+address new problems or concerns.
+
+Each version is given a distinguishing version number. If the Program
+specifies a version number of this License which applies to it and "any
+later version", you have the option of following the terms and conditions
+either of that version or of any later version published by the Free
+Software Foundation. If the Program does not specify a version number of
+this License, you may choose any version ever published by the Free Software
+Foundation.
+
+ 10. If you wish to incorporate parts of the Program into other free
+programs whose distribution conditions are different, write to the author
+to ask for permission. For software which is copyrighted by the Free
+Software Foundation, write to the Free Software Foundation; we sometimes
+make exceptions for this. Our decision will be guided by the two goals
+of preserving the free status of all derivatives of our free software and
+of promoting the sharing and reuse of software generally.
+
+ NO WARRANTY
+
+ 11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
+FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN
+OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
+PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
+OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
+MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS
+TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE
+PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
+REPAIR OR CORRECTION.
+
+ 12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
+WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
+REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
+INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
+OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
+TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
+YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
+PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
+POSSIBILITY OF SUCH DAMAGES.
+
+ END OF TERMS AND CONDITIONS
+
+ How to Apply These Terms to Your New Programs
+
+ If you develop a new program, and you want it to be of the greatest
+possible use to the public, the best way to achieve this is to make it
+free software which everyone can redistribute and change under these terms.
+
+ To do so, attach the following notices to the program. It is safest
+to attach them to the start of each source file to most effectively
+convey the exclusion of warranty; and each file should have at least
+the "copyright" line and a pointer to where the full notice is found.
+
+ <one line to give the program's name and a brief idea of what it does.>
+ Copyright (C) <year> <name of author>
+
+ This program is free software; you can redistribute it and/or modify
+ it under the terms of the GNU General Public License as published by
+ the Free Software Foundation; either version 2 of the License, or
+ (at your option) any later version.
+
+ This program is distributed in the hope that it will be useful,
+ but WITHOUT ANY WARRANTY; without even the implied warranty of
+ MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the
+ GNU General Public License for more details.
+
+ You should have received a copy of the GNU General Public License
+ along with this program; if not, write to the Free Software
+ Foundation, Inc., 51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA
+
+
+Also add information on how to contact you by electronic and paper mail.
+
+If the program is interactive, make it output a short notice like this
+when it starts in an interactive mode:
+
+ Gnomovision version 69, Copyright (C) year name of author
+ Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
+ This is free software, and you are welcome to redistribute it
+ under certain conditions; type `show c' for details.
+
+The hypothetical commands `show w' and `show c' should show the appropriate
+parts of the General Public License. Of course, the commands you use may
+be called something other than `show w' and `show c'; they could even be
+mouse-clicks or menu items--whatever suits your program.
+
+You should also get your employer (if you work as a programmer) or your
+school, if any, to sign a "copyright disclaimer" for the program, if
+necessary. Here is a sample; alter the names:
+
+ Yoyodyne, Inc., hereby disclaims all copyright interest in the program
+ `Gnomovision' (which makes passes at compilers) written by James Hacker.
+
+ <signature of Ty Coon>, 1 April 1989
+ Ty Coon, President of Vice
+
+This General Public License does not permit incorporating your program into
+proprietary programs. If your program is a subroutine library, you may
+consider it more useful to permit linking proprietary applications with the
+library. If this is what you want to do, use the GNU Lesser General
+Public License instead of this License.

+ *
+ * There's a long-standing bug in that self-intersecting paths give
+ * an incorrect result when stroked. The problem is that the
+ * trapezoids are generated incrementally along the stroke and as
+ * such, are not disjoint. The errant intersections of these
+ * trapezoids then leads to overfilled pixels.
+ *
+ * The test belows first creates and fills a path. Then it creates a
+ * second path which has a stroked boundary identical to the first
+ * filled path. But the results of the two operations are
+ * different. The most obvious difference is in the central region
+ * where the entire path intersects itself. But notice that every
+ * time the path turns there are also errors on the inside of the
+ * turn, (since the subsequent trapezoids along the path intersect).

+/* Bug history
+ *
+ * 2006-01-07 Jon Hellan <hellan@acm.org>
+ *
+ * Jon opened the following bug report:
+ *
+ * _XError from XRenderCompositeText8
+ * https://bugs.freedesktop.org/show_bug.cgi?id=5528
+ *
+ * 2006-03-02 Carl Worth <cworth@cworth.org>
+ *
+ * I wrote this test case to demonstrate the bug.
+ *
+ * Approach:
+ *
+ * Draw 65535 glyphs white-on-white all on top of each other.
+ *
+ * Rationale:
+ *
+ * The number 65535 comes from the original bug report.
+ *
+ * I would use cairo_show_text with a long string of 'x's say,
+ * but then the surface would need to be enormous to contain
+ * them. A smaller surface could be used, but I fear that at some
+ * point the off-surface glyph drawing would be optimized away
+ * and not exercise the bug.
+ *
+ * So, to keep the surface size under control, I use
+ * cairo_show_glyphs which allows me to place the glyphs all on
+ * top of each other. But, since cairo doesn't provide any
+ * character-to-glyphs mapping, I can't get a reliable glyph
+ * index (for character 'x' for example). So I just "guess" a
+ * glyph index and use white-on-white drawing to ignore the
+ * result. (I don't care what's drawn---I just want to ensure
+ * that things don't crash.)

+ * \ \
+ * \ \
+ * \ \

+ * d\_\c

+ * edge is left of the ad edge. The fix is simply to compare c.x to

+ * Subject: [cairo] Rotated text bug on drawable target
+ *
+ * The attached file draws text rotated 90 degrees first to a PNG file and
+ * then to a drawable. The PNG file looks fine, the text on the drawable is
+ * unreadable.
+ *

+ *
+ * 2004-11-03 Carl Worth <cworth@cworth.org>
+ *
+ * Looks like the major problems with this bug appeared in the great
+ * font rework between 0.1.23 and 0.2.0. And it looks like we need
+ * to fix the regression test suite to test the xlib target (since
+ * the bug does not show up in the png backend).
+ *
+ * Hmm... Actually, things don't look perfect even in the PNG
+ * output. Look at how that 'o' moves around. It's particularly off
+ * in the case where it's rotated by PI.
+ *
+ * And I'm still not sure about what to do for test cases with
+ * text--a new version of freetype will change everything. We may
+ * need to add a simple backend for stroked fonts and add a simple
+ * builtin font to cairo for pixel-perfect tests with text.
+ *
+ * 2005-08-23
+ *
+ * It appears that the worst placement and glyph selection problems
+ * have now been resolved. In the past some letters were noticeably
+ * of a different size at some rotations, and there was a lot of
+ * drift away from the baseline. These problems do not appear
+ * anymore.
+ *
+ * Another thing that helps is that we now have font options which
+ * we can use to disable hinting in order to get more repeatable
+ * results. I'm doing that in this test now.
+ *
+ * There are still some subtle positioning problems which I'm
+ * assuming are due to the lack of finer-than-whole-pixel glyph
+ * positioning. I'm generating a reference image now by replacing
+ * cairo_show_text with cairo_text_path; cairo_fill. This will let
+ * us look more closely at the remaining positioning problems. (In
+ * particular, I want to make sure we're rounding as well as
+ * possible).
+ *
+ * 2007-02-21
+ *
+ * Seems like all the "bugs" have been fixed and all remaining is
+ * missing support for subpixel glyph positioning. Removing from
+ * XFAIL now.

+ *
+ * Moreover, the fallback path in cairo_scaled_font_text_to_glyphs()

+ *
+ * It appears that calling cairo_show_surface after cairo_translate
+ * somehow applies the translation twice to the surface being
+ * shown. This is pretty easy to demonstrate by bringing up xsvg on
+ * an SVG file with an <image> and panning around a bit with the
+ * arrow keys.
+ *
+ * This is almost certainly a regression, and I suspect there may be
+ * some interaction with the fix for move-to-show-surface.

+ A hacky replacement for backtrace_symbols in glibc
+
+ backtrace_symbols in glibc looks up symbols using dladdr which is limited in
+ the symbols that it sees. libbacktracesymbols opens the executable and shared
+ libraries using libbfd and will look up backtrace information using the symbol
+ table and the dwarf line information.
+
+ It may make more sense for this program to use libelf instead of libbfd.
+ However, I have not investigated that yet.

+ GNU GENERAL PUBLIC LICENSE
+ Version 3, 29 June 2007
+
+ Copyright (C) 2007 Free Software Foundation, Inc. <http://fsf.org/>
+ Everyone is permitted to copy and distribute verbatim copies
+ of this license document, but changing it is not allowed.
+
+ Preamble
+
+ The GNU General Public License is a free, copyleft license for
+software and other kinds of works.
+
+ The licenses for most software and other practical works are designed
+to take away your freedom to share and change the works. By contrast,
+the GNU General Public License is intended to guarantee your freedom to
+share and change all versions of a program--to make sure it remains free
+software for all its users. We, the Free Software Foundation, use the
+GNU General Public License for most of our software; it applies also to
+any other work released this way by its authors. You can apply it to
+your programs, too.
+
+ When we speak of free software, we are referring to freedom, not
+price. Our General Public Licenses are designed to make sure that you
+have the freedom to distribute copies of free software (and charge for
+them if you wish), that you receive source code or can get it if you
+want it, that you can change the software or use pieces of it in new
+free programs, and that you know you can do these things.
+
+ To protect your rights, we need to prevent others from denying you
+these rights or asking you to surrender the rights. Therefore, you have
+certain responsibilities if you distribute copies of the software, or if
+you modify it: responsibilities to respect the freedom of others.
+
+ For example, if you distribute copies of such a program, whether
+gratis or for a fee, you must pass on to the recipients the same
+freedoms that you received. You must make sure that they, too, receive
+or can get the source code. And you must show them these terms so they
+know their rights.
+
+ Developers that use the GNU GPL protect your rights with two steps:
+(1) assert copyright on the software, and (2) offer you this License
+giving you legal permission to copy, distribute and/or modify it.
+
+ For the developers' and authors' protection, the GPL clearly explains
+that there is no warranty for this free software. For both users' and
+authors' sake, the GPL requires that modified versions be marked as
+changed, so that their problems will not be attributed erroneously to
+authors of previous versions.
+
+ Some devices are designed to deny users access to install or run
+modified versions of the software inside them, although the manufacturer
+can do so. This is fundamentally incompatible with the aim of
+protecting users' freedom to change the software. The systematic
+pattern of such abuse occurs in the area of products for individuals to
+use, which is precisely where it is most unacceptable. Therefore, we
+have designed this version of the GPL to prohibit the practice for those
+products. If such problems arise substantially in other domains, we
+stand ready to extend this provision to those domains in future versions
+of the GPL, as needed to protect the freedom of users.
+
+ Finally, every program is threatened constantly by software patents.
+States should not allow patents to restrict development and use of
+software on general-purpose computers, but in those that do, we wish to
+avoid the special danger that patents applied to a free program could
+make it effectively proprietary. To prevent this, the GPL assures that
+patents cannot be used to render the program non-free.
+
+ The precise terms and conditions for copying, distribution and
+modification follow.
+
+ TERMS AND CONDITIONS
+
+ 0. Definitions.
+
+ "This License" refers to version 3 of the GNU General Public License.
+
+ "Copyright" also means copyright-like laws that apply to other kinds of
+works, such as semiconductor masks.
+
+ "The Program" refers to any copyrightable work licensed under this
+License. Each licensee is addressed as "you". "Licensees" and
+"recipients" may be individuals or organizations.
+
+ To "modify" a work means to copy from or adapt all or part of the work
+in a fashion requiring copyright permission, other than the making of an
+exact copy. The resulting work is called a "modified version" of the
+earlier work or a work "based on" the earlier work.
+
+ A "covered work" means either the unmodified Program or a work based
+on the Program.
+
+ To "propagate" a work means to do anything with it that, without
+permission, would make you directly or secondarily liable for
+infringement under applicable copyright law, except executing it on a
+computer or modifying a private copy. Propagation includes copying,
+distribution (with or without modification), making available to the
+public, and in some countries other activities as well.
+
+ To "convey" a work means any kind of propagation that enables other
+parties to make or receive copies. Mere interaction with a user through
+a computer network, with no transfer of a copy, is not conveying.
+
+ An interactive user interface displays "Appropriate Legal Notices"
+to the extent that it includes a convenient and prominently visible
+feature that (1) displays an appropriate copyright notice, and (2)
+tells the user that there is no warranty for the work (except to the
+extent that warranties are provided), that licensees may convey the
+work under this License, and how to view a copy of this License. If
+the interface presents a list of user commands or options, such as a
+menu, a prominent item in the list meets this criterion.
+
+ 1. Source Code.
+
+ The "source code" for a work means the preferred form of the work
+for making modifications to it. "Object code" means any non-source
+form of a work.
+
+ A "Standard Interface" means an interface that either is an official
+standard defined by a recognized standards body, or, in the case of
+interfaces specified for a particular programming language, one that
+is widely used among developers working in that language.
+
+ The "System Libraries" of an executable work include anything, other
+than the work as a whole, that (a) is included in the normal form of
+packaging a Major Component, but which is not part of that Major
+Component, and (b) serves only to enable use of the work with that
+Major Component, or to implement a Standard Interface for which an
+implementation is available to the public in source code form. A
+"Major Component", in this context, means a major essential component
+(kernel, window system, and so on) of the specific operating system
+(if any) on which the executable work runs, or a compiler used to
+produce the work, or an object code interpreter used to run it.
+
+ The "Corresponding Source" for a work in object code form means all
+the source code needed to generate, install, and (for an executable
+work) run the object code and to modify the work, including scripts to
+control those activities. However, it does not include the work's
+System Libraries, or general-purpose tools or generally available free
+programs which are used unmodified in performing those activities but
+which are not part of the work. For example, Corresponding Source
+includes interface definition files associated with source files for
+the work, and the source code for shared libraries and dynamically
+linked subprograms that the work is specifically designed to require,
+such as by intimate data communication or control flow between those
+subprograms and other parts of the work.
+
+ The Corresponding Source need not include anything that users
+can regenerate automatically from other parts of the Corresponding
+Source.
+
+ The Corresponding Source for a work in source code form is that
+same work.
+
+ 2. Basic Permissions.
+
+ All rights granted under this License are granted for the term of
+copyright on the Program, and are irrevocable provided the stated
+conditions are met. This License explicitly affirms your unlimited
+permission to run the unmodified Program. The output from running a
+covered work is covered by this License only if the output, given its
+content, constitutes a covered work. This License acknowledges your
+rights of fair use or other equivalent, as provided by copyright law.
+
+ You may make, run and propagate covered works that you do not
+convey, without conditions so long as your license otherwise remains
+in force. You may convey covered works to others for the sole purpose
+of having them make modifications exclusively for you, or provide you
+with facilities for running those works, provided that you comply with
+the terms of this License in conveying all material for which you do
+not control copyright. Those thus making or running the covered works
+for you must do so exclusively on your behalf, under your direction
+and control, on terms that prohibit them from making any copies of
+your copyrighted material outside their relationship with you.
+
+ Conveying under any other circumstances is permitted solely under
+the conditions stated below. Sublicensing is not allowed; section 10
+makes it unnecessary.
+
+ 3. Protecting Users' Legal Rights From Anti-Circumvention Law.
+
+ No covered work shall be deemed part of an effective technological
+measure under any applicable law fulfilling obligations under article
+11 of the WIPO copyright treaty adopted on 20 December 1996, or
+similar laws prohibiting or restricting circumvention of such
+measures.
+
+ When you convey a covered work, you waive any legal power to forbid
+circumvention of technological measures to the extent such circumvention
+is effected by exercising rights under this License with respect to
+the covered work, and you disclaim any intention to limit operation or
+modification of the work as a means of enforcing, against the work's
+users, your or third parties' legal rights to forbid circumvention of
+technological measures.
+
+ 4. Conveying Verbatim Copies.
+
+ You may convey verbatim copies of the Program's source code as you
+receive it, in any medium, provided that you conspicuously and
+appropriately publish on each copy an appropriate copyright notice;
+keep intact all notices stating that this License and any
+non-permissive terms added in accord with section 7 apply to the code;
+keep intact all notices of the absence of any warranty; and give all
+recipients a copy of this License along with the Program.
+
+ You may charge any price or no price for each copy that you convey,
+and you may offer support or warranty protection for a fee.
+
+ 5. Conveying Modified Source Versions.
+
+ You may convey a work based on the Program, or the modifications to
+produce it from the Program, in the form of source code under the
+terms of section 4, provided that you also meet all of these conditions:
+
+ a) The work must carry prominent notices stating that you modified
+ it, and giving a relevant date.
+
+ b) The work must carry prominent notices stating that it is
+ released under this License and any conditions added under section
+ 7. This requirement modifies the requirement in section 4 to
+ "keep intact all notices".
+
+ c) You must license the entire work, as a whole, under this
+ License to anyone who comes into possession of a copy. This
+ License will therefore apply, along with any applicable section 7
+ additional terms, to the whole of the work, and all its parts,
+ regardless of how they are packaged. This License gives no
+ permission to license the work in any other way, but it does not
+ invalidate such permission if you have separately received it.
+
+ d) If the work has interactive user interfaces, each must display
+ Appropriate Legal Notices; however, if the Program has interactive
+ interfaces that do not display Appropriate Legal Notices, your
+ work need not make them do so.
+
+ A compilation of a covered work with other separate and independent
+works, which are not by their nature extensions of the covered work,
+and which are not combined with it such as to form a larger program,
+in or on a volume of a storage or distribution medium, is called an
+"aggregate" if the compilation and its resulting copyright are not
+used to limit the access or legal rights of the compilation's users
+beyond what the individual works permit. Inclusion of a covered work
+in an aggregate does not cause this License to apply to the other
+parts of the aggregate.
+
+ 6. Conveying Non-Source Forms.
+
+ You may convey a covered work in object code form under the terms
+of sections 4 and 5, provided that you also convey the
+machine-readable Corresponding Source under the terms of this License,
+in one of these ways:
+
+ a) Convey the object code in, or embodied in, a physical product
+ (including a physical distribution medium), accompanied by the
+ Corresponding Source fixed on a durable physical medium
+ customarily used for software interchange.
+
+ b) Convey the object code in, or embodied in, a physical product
+ (including a physical distribution medium), accompanied by a
+ written offer, valid for at least three years and valid for as
+ long as you offer spare parts or customer support for that product
+ model, to give anyone who possesses the object code either (1) a
+ copy of the Corresponding Source for all the software in the
+ product that is covered by this License, on a durable physical
+ medium customarily used for software interchange, for a price no
+ more than your reasonable cost of physically performing this
+ conveying of source, or (2) access to copy the
+ Corresponding Source from a network server at no charge.
+
+ c) Convey individual copies of the object code with a copy of the
+ written offer to provide the Corresponding Source. This
+ alternative is allowed only occasionally and noncommercially, and
+ only if you received the object code with such an offer, in accord
+ with subsection 6b.
+
+ d) Convey the object code by offering access from a designated
+ place (gratis or for a charge), and offer equivalent access to the
+ Corresponding Source in the same way through the same place at no
+ further charge. You need not require recipients to copy the
+ Corresponding Source along with the object code. If the place to
+ copy the object code is a network server, the Corresponding Source
+ may be on a different server (operated by you or a third party)
+ that supports equivalent copying facilities, provided you maintain
+ clear directions next to the object code saying where to find the
+ Corresponding Source. Regardless of what server hosts the
+ Corresponding Source, you remain obligated to ensure that it is
+ available for as long as needed to satisfy these requirements.
+
+ e) Convey the object code using peer-to-peer transmission, provided
+ you inform other peers where the object code and Corresponding
+ Source of the work are being offered to the general public at no
+ charge under subsection 6d.
+
+ A separable portion of the object code, whose source code is excluded
+from the Corresponding Source as a System Library, need not be
+included in conveying the object code work.
+
+ A "User Product" is either (1) a "consumer product", which means any
+tangible personal property which is normally used for personal, family,
+or household purposes, or (2) anything designed or sold for incorporation
+into a dwelling. In determining whether a product is a consumer product,
+doubtful cases shall be resolved in favor of coverage. For a particular
+product received by a particular user, "normally used" refers to a
+typical or common use of that class of product, regardless of the status
+of the particular user or of the way in which the particular user
+actually uses, or expects or is expected to use, the product. A product
+is a consumer product regardless of whether the product has substantial
+commercial, industrial or non-consumer uses, unless such uses represent
+the only significant mode of use of the product.
+
+ "Installation Information" for a User Product means any methods,
+procedures, authorization keys, or other information required to install
+and execute modified versions of a covered work in that User Product from
+a modified version of its Corresponding Source. The information must
+suffice to ensure that the continued functioning of the modified object
+code is in no case prevented or interfered with solely because
+modification has been made.
+
+ If you convey an object code work under this section in, or with, or
+specifically for use in, a User Product, and the conveying occurs as
+part of a transaction in which the right of possession and use of the
+User Product is transferred to the recipient in perpetuity or for a
+fixed term (regardless of how the transaction is characterized), the
+Corresponding Source conveyed under this section must be accompanied
+by the Installation Information. But this requirement does not apply
+if neither you nor any third party retains the ability to install
+modified object code on the User Product (for example, the work has
+been installed in ROM).
+
+ The requirement to provide Installation Information does not include a
+requirement to continue to provide support service, warranty, or updates
+for a work that has been modified or installed by the recipient, or for
+the User Product in which it has been modified or installed. Access to a
+network may be denied when the modification itself materially and
+adversely affects the operation of the network or violates the rules and
+protocols for communication across the network.
+
+ Corresponding Source conveyed, and Installation Information provided,
+in accord with this section must be in a format that is publicly
+documented (and with an implementation available to the public in
+source code form), and must require no special password or key for
+unpacking, reading or copying.
+
+ 7. Additional Terms.
+
+ "Additional permissions" are terms that supplement the terms of this
+License by making exceptions from one or more of its conditions.
+Additional permissions that are applicable to the entire Program shall
+be treated as though they were included in this License, to the extent
+that they are valid under applicable law. If additional permissions
+apply only to part of the Program, that part may be used separately
+under those permissions, but the entire Program remains governed by
+this License without regard to the additional permissions.
+
+ When you convey a copy of a covered work, you may at your option
+remove any additional permissions from that copy, or from any part of
+it. (Additional permissions may be written to require their own
+removal in certain cases when you modify the work.) You may place
+additional permissions on material, added by you to a covered work,
+for which you have or can give appropriate copyright permission.
+
+ Notwithstanding any other provision of this License, for material you
+add to a covered work, you may (if authorized by the copyright holders of
+that material) supplement the terms of this License with terms:
+
+ a) Disclaiming warranty or limiting liability differently from the
+ terms of sections 15 and 16 of this License; or
+
+ b) Requiring preservation of specified reasonable legal notices or
+ author attributions in that material or in the Appropriate Legal
+ Notices displayed by works containing it; or
+
+ c) Prohibiting misrepresentation of the origin of that material, or
+ requiring that modified versions of such material be marked in
+ reasonable ways as different from the original version; or
+
+ d) Limiting the use for publicity purposes of names of licensors or
+ authors of the material; or
+
+ e) Declining to grant rights under trademark law for use of some
+ trade names, trademarks, or service marks; or
+
+ f) Requiring indemnification of licensors and authors of that
+ material by anyone who conveys the material (or modified versions of
+ it) with contractual assumptions of liability to the recipient, for
+ any liability that these contractual assumptions directly impose on
+ those licensors and authors.
+
+ All other non-permissive additional terms are considered "further
+restrictions" within the meaning of section 10. If the Program as you
+received it, or any part of it, contains a notice stating that it is
+governed by this License along with a term that is a further
+restriction, you may remove that term. If a license document contains
+a further restriction but permits relicensing or conveying under this
+License, you may add to a covered work material governed by the terms
+of that license document, provided that the further restriction does
+not survive such relicensing or conveying.
+
+ If you add terms to a covered work in accord with this section, you
+must place, in the relevant source files, a statement of the
+additional terms that apply to those files, or a notice indicating
+where to find the applicable terms.
+
+ Additional terms, permissive or non-permissive, may be stated in the
+form of a separately written license, or stated as exceptions;
+the above requirements apply either way.
+
+ 8. Termination.
+
+ You may not propagate or modify a covered work except as expressly
+provided under this License. Any attempt otherwise to propagate or
+modify it is void, and will automatically terminate your rights under
+this License (including any patent licenses granted under the third
+paragraph of section 11).
+
+ However, if you cease all violation of this License, then your
+license from a particular copyright holder is reinstated (a)
+provisionally, unless and until the copyright holder explicitly and
+finally terminates your license, and (b) permanently, if the copyright
+holder fails to notify you of the violation by some reasonable means
+prior to 60 days after the cessation.
+
+ Moreover, your license from a particular copyright holder is
+reinstated permanently if the copyright holder notifies you of the
+violation by some reasonable means, this is the first time you have
+received notice of violation of this License (for any work) from that
+copyright holder, and you cure the violation prior to 30 days after
+your receipt of the notice.
+
+ Termination of your rights under this section does not terminate the
+licenses of parties who have received copies or rights from you under
+this License. If your rights have been terminated and not permanently
+reinstated, you do not qualify to receive new licenses for the same
+material under section 10.
+
+ 9. Acceptance Not Required for Having Copies.
+
+ You are not required to accept this License in order to receive or
+run a copy of the Program. Ancillary propagation of a covered work
+occurring solely as a consequence of using peer-to-peer transmission
+to receive a copy likewise does not require acceptance. However,
+nothing other than this License grants you permission to propagate or
+modify any covered work. These actions infringe copyright if you do
+not accept this License. Therefore, by modifying or propagating a
+covered work, you indicate your acceptance of this License to do so.
+
+ 10. Automatic Licensing of Downstream Recipients.
+
+ Each time you convey a covered work, the recipient automatically
+receives a license from the original licensors, to run, modify and
+propagate that work, subject to this License. You are not responsible
+for enforcing compliance by third parties with this License.
+
+ An "entity transaction" is a transaction transferring control of an
+organization, or substantially all assets of one, or subdividing an
+organization, or merging organizations. If propagation of a covered
+work results from an entity transaction, each party to that
+transaction who receives a copy of the work also receives whatever
+licenses to the work the party's predecessor in interest had or could
+give under the previous paragraph, plus a right to possession of the
+Corresponding Source of the work from the predecessor in interest, if
+the predecessor has it or can get it with reasonable efforts.
+
+ You may not impose any further restrictions on the exercise of the
+rights granted or affirmed under this License. For example, you may
+not impose a license fee, royalty, or other charge for exercise of
+rights granted under this License, and you may not initiate litigation
+(including a cross-claim or counterclaim in a lawsuit) alleging that
+any patent claim is infringed by making, using, selling, offering for
+sale, or importing the Program or any portion of it.
+
+ 11. Patents.
+
+ A "contributor" is a copyright holder who authorizes use under this
+License of the Program or a work on which the Program is based. The
+work thus licensed is called the contributor's "contributor version".
+
+ A contributor's "essential patent claims" are all patent claims
+owned or controlled by the contributor, whether already acquired or
+hereafter acquired, that would be infringed by some manner, permitted
+by this License, of making, using, or selling its contributor version,
+but do not include claims that would be infringed only as a
+consequence of further modification of the contributor version. For
+purposes of this definition, "control" includes the right to grant
+patent sublicenses in a manner consistent with the requirements of
+this License.
+
+ Each contributor grants you a non-exclusive, worldwide, royalty-free
+patent license under the contributor's essential patent claims, to
+make, use, sell, offer for sale, import and otherwise run, modify and
+propagate the contents of its contributor version.
+
+ In the following three paragraphs, a "patent license" is any express
+agreement or commitment, however denominated, not to enforce a patent
+(such as an express permission to practice a patent or covenant not to
+sue for patent infringement). To "grant" such a patent license to a
+party means to make such an agreement or commitment not to enforce a
+patent against the party.
+
+ If you convey a covered work, knowingly relying on a patent license,
+and the Corresponding Source of the work is not available for anyone
+to copy, free of charge and under the terms of this License, through a
+publicly available network server or other readily accessible means,
+then you must either (1) cause the Corresponding Source to be so
+available, or (2) arrange to deprive yourself of the benefit of the
+patent license for this particular work, or (3) arrange, in a manner
+consistent with the requirements of this License, to extend the patent
+license to downstream recipients. "Knowingly relying" means you have
+actual knowledge that, but for the patent license, your conveying the
+covered work in a country, or your recipient's use of the covered work
+in a country, would infringe one or more identifiable patents in that
+country that you have reason to believe are valid.
+
+ If, pursuant to or in connection with a single transaction or
+arrangement, you convey, or propagate by procuring conveyance of, a
+covered work, and grant a patent license to some of the parties
+receiving the covered work authorizing them to use, propagate, modify
+or convey a specific copy of the covered work, then the patent license
+you grant is automatically extended to all recipients of the covered
+work and works based on it.
+
+ A patent license is "discriminatory" if it does not include within
+the scope of its coverage, prohibits the exercise of, or is
+conditioned on the non-exercise of one or more of the rights that are
+specifically granted under this License. You may not convey a covered
+work if you are a party to an arrangement with a third party that is
+in the business of distributing software, under which you make payment
+to the third party based on the extent of your activity of conveying
+the work, and under which the third party grants, to any of the
+parties who would receive the covered work from you, a discriminatory
+patent license (a) in connection with copies of the covered work
+conveyed by you (or copies made from those copies), or (b) primarily
+for and in connection with specific products or compilations that
+contain the covered work, unless you entered into that arrangement,
+or that patent license was granted, prior to 28 March 2007.
+
+ Nothing in this License shall be construed as excluding or limiting
+any implied license or other defenses to infringement that may
+otherwise be available to you under applicable patent law.
+
+ 12. No Surrender of Others' Freedom.
+
+ If conditions are imposed on you (whether by court order, agreement or
+otherwise) that contradict the conditions of this License, they do not
+excuse you from the conditions of this License. If you cannot convey a
+covered work so as to satisfy simultaneously your obligations under this
+License and any other pertinent obligations, then as a consequence you may
+not convey it at all. For example, if you agree to terms that obligate you
+to collect a royalty for further conveying from those to whom you convey
+the Program, the only way you could satisfy both those terms and this
+License would be to refrain entirely from conveying the Program.
+
+ 13. Use with the GNU Affero General Public License.
+
+ Notwithstanding any other provision of this License, you have
+permission to link or combine any covered work with a work licensed
+under version 3 of the GNU Affero General Public License into a single
+combined work, and to convey the resulting work. The terms of this
+License will continue to apply to the part which is the covered work,
+but the special requirements of the GNU Affero General Public License,
+section 13, concerning interaction through a network will apply to the
+combination as such.
+
+ 14. Revised Versions of this License.
+
+ The Free Software Foundation may publish revised and/or new versions of
+the GNU General Public License from time to time. Such new versions will
+be similar in spirit to the present version, but may differ in detail to
+address new problems or concerns.
+
+ Each version is given a distinguishing version number. If the
+Program specifies that a certain numbered version of the GNU General
+Public License "or any later version" applies to it, you have the
+option of following the terms and conditions either of that numbered
+version or of any later version published by the Free Software
+Foundation. If the Program does not specify a version number of the
+GNU General Public License, you may choose any version ever published
+by the Free Software Foundation.
+
+ If the Program specifies that a proxy can decide which future
+versions of the GNU General Public License can be used, that proxy's
+public statement of acceptance of a version permanently authorizes you
+to choose that version for the Program.
+
+ Later license versions may give you additional or different
+permissions. However, no additional obligations are imposed on any
+author or copyright holder as a result of your choosing to follow a
+later version.
+
+ 15. Disclaimer of Warranty.
+
+ THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY
+APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT
+HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY
+OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO,
+THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
+PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM
+IS WITH YOU. SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF
+ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
+
+ 16. Limitation of Liability.
+
+ IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
+WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS
+THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY
+GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE
+USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF
+DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD
+PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS),
+EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF
+SUCH DAMAGES.
+
+ 17. Interpretation of Sections 15 and 16.
+
+ If the disclaimer of warranty and limitation of liability provided
+above cannot be given local legal effect according to their terms,
+reviewing courts shall apply local law that most closely approximates
+an absolute waiver of all civil liability in connection with the
+Program, unless a warranty or assumption of liability accompanies a
+copy of the Program in return for a fee.
+
+ END OF TERMS AND CONDITIONS
+
+ How to Apply These Terms to Your New Programs
+
+ If you develop a new program, and you want it to be of the greatest
+possible use to the public, the best way to achieve this is to make it
+free software which everyone can redistribute and change under these terms.
+
+ To do so, attach the following notices to the program. It is safest
+to attach them to the start of each source file to most effectively
+state the exclusion of warranty; and each file should have at least
+the "copyright" line and a pointer to where the full notice is found.
+
+ <one line to give the program's name and a brief idea of what it does.>
+ Copyright (C) <year> <name of author>
+
+ This program is free software: you can redistribute it and/or modify
+ it under the terms of the GNU General Public License as published by
+ the Free Software Foundation, either version 3 of the License, or
+ (at your option) any later version.
+
+ This program is distributed in the hope that it will be useful,
+ but WITHOUT ANY WARRANTY; without even the implied warranty of
+ MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the
+ GNU General Public License for more details.
+
+ You should have received a copy of the GNU General Public License
+ along with this program. If not, see <http://www.gnu.org/licenses/>.
+
+Also add information on how to contact you by electronic and paper mail.
+
+ If the program does terminal interaction, make it output a short
+notice like this when it starts in an interactive mode:
+
+ <program> Copyright (C) <year> <name of author>
+ This program comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
+ This is free software, and you are welcome to redistribute it
+ under certain conditions; type `show c' for details.
+
+The hypothetical commands `show w' and `show c' should show the appropriate
+parts of the General Public License. Of course, your program's commands
+might be different; for a GUI interface, you would use an "about box".
+
+ You should also get your employer (if you work as a programmer) or school,
+if any, to sign a "copyright disclaimer" for the program, if necessary.
+For more information on this, and how to apply and follow the GNU GPL, see
+<http://www.gnu.org/licenses/>.
+
+ The GNU General Public License does not permit incorporating your program
+into proprietary programs. If your program is a subroutine library, you
+may consider it more useful to permit linking proprietary applications with
+the library. If this is what you want to do, use the GNU Lesser General
+Public License instead of this License. But first, please read
+<http://www.gnu.org/philosophy/why-not-lgpl.html>.
