+ Use only one toplevel .gitignore file.
+
+ It was tempting to also modify the code to not, first check if
+ xrender is >= 0.8.2, and then, if failing, check for libXrender
+ functions with different build options, but left as is, as it
+ could be somehow useful at least as an example of being backwards
+ compatible.

+
+ XftFontOpenInfo: Use of uninitialised value of size 8 (bug 11200)
+
+ This is due to XftFontInfoFill using the binary representation of the
+ XftFontInfo to generate fi->hash.
+
+ With 64-bit pointers there is padding between .hash and .file in struct
+ _XftFontInfo. This padding is not initialized, and the hash uses these
+ bytes.
+
+ This will interfere with finding "a matching previously opened font" in
+ XftFontOpenInfo, and XftFontInfoEqual, which uses memcmp, will have similar
+ problems.
+
+ This fix makes no assumptions about the sizes and alignment of members of
+ struct _XftFontInfo by using memset. (It also makes no assumptions about
+ what FcPatternGet* does to its output parameter when it returns
+ FcResultNoMatch.)

+
+ gcc4 allows to check if sentinels are correct (a sentinel is the
+ terminating element in a varargs list). A sentinel needs to be NULL,
+ not 0 - which doesn't make a difference on 32bit but matters on 64bit.
+ Furthermore it can be told that functions have a printf-like format
+ string and argument list so that they can verify that both match. To
+ use these features certain attributes need to be set - which are
+ compiler specific. To do this we define macros which are expanded
+ depending on the compiler version. For now we put those in
+ include/Xfuncproto.h (the XFree86 DDX layer contains a file compiler.h
+ which however is not visible outside the DDX) (Bugzilla #3268).

+
+Copyright (C) 1994, 1995, 1996, 1999, 2000, 2001, 2002, 2004, 2005,
+2006, 2007, 2008 Free Software Foundation, Inc.
+
+ This file is free documentation; the Free Software Foundation gives
+unlimited permission to copy, distribute and modify it.
+
+Basic Installation
+==================
+
+ Briefly, the shell commands `./configure; make; make install' should
+configure, build, and install this package. The following
+more-detailed instructions are generic; see the `README' file for
+instructions specific to this package.
+
+ The `configure' shell script attempts to guess correct values for
+various system-dependent variables used during compilation. It uses
+those values to create a `Makefile' in each directory of the package.
+It may also create one or more `.h' files containing system-dependent
+definitions. Finally, it creates a shell script `config.status' that
+you can run in the future to recreate the current configuration, and a
+file `config.log' containing compiler output (useful mainly for
+debugging `configure').
+
+ It can also use an optional file (typically called `config.cache'
+and enabled with `--cache-file=config.cache' or simply `-C') that saves
+the results of its tests to speed up reconfiguring. Caching is
+disabled by default to prevent problems with accidental use of stale
+cache files.
+
+ If you need to do unusual things to compile the package, please try
+to figure out how `configure' could check whether to do them, and mail
+diffs or instructions to the address given in the `README' so they can
+be considered for the next release. If you are using the cache, and at
+some point `config.cache' contains results you don't want to keep, you
+may remove or edit it.
+
+ The file `configure.ac' (or `configure.in') is used to create
+`configure' by a program called `autoconf'. You need `configure.ac' if
+you want to change it or regenerate `configure' using a newer version
+of `autoconf'.
+
+The simplest way to compile this package is:
+
+ 1. `cd' to the directory containing the package's source code and type
+ `./configure' to configure the package for your system.
+
+ Running `configure' might take a while. While running, it prints
+ some messages telling which features it is checking for.
+
+ 2. Type `make' to compile the package.
+
+ 3. Optionally, type `make check' to run any self-tests that come with
+ the package.
+
+ 4. Type `make install' to install the programs and any data files and
+ documentation.
+
+ 5. You can remove the program binaries and object files from the
+ source code directory by typing `make clean'. To also remove the
+ files that `configure' created (so you can compile the package for
+ a different kind of computer), type `make distclean'. There is
+ also a `make maintainer-clean' target, but that is intended mainly
+ for the package's developers. If you use it, you may have to get
+ all sorts of other programs in order to regenerate files that came
+ with the distribution.
+
+ 6. Often, you can also type `make uninstall' to remove the installed
+ files again.
+
+Compilers and Options
+=====================
+
+ Some systems require unusual options for compilation or linking that
+the `configure' script does not know about. Run `./configure --help'
+for details on some of the pertinent environment variables.
+
+ You can give `configure' initial values for configuration parameters
+by setting variables in the command line or in the environment. Here
+is an example:
+
+ ./configure CC=c99 CFLAGS=-g LIBS=-lposix
+
+ *Note Defining Variables::, for more details.
+
+Compiling For Multiple Architectures
+====================================
+
+ You can compile the package for more than one kind of computer at the
+same time, by placing the object files for each architecture in their
+own directory. To do this, you can use GNU `make'. `cd' to the
+directory where you want the object files and executables to go and run
+the `configure' script. `configure' automatically checks for the
+source code in the directory that `configure' is in and in `..'.
+
+ With a non-GNU `make', it is safer to compile the package for one
+architecture at a time in the source code directory. After you have
+installed the package for one architecture, use `make distclean' before
+reconfiguring for another architecture.
+
+ On MacOS X 10.5 and later systems, you can create libraries and
+executables that work on multiple system types--known as "fat" or
+"universal" binaries--by specifying multiple `-arch' options to the
+compiler but only a single `-arch' option to the preprocessor. Like
+this:
+
+ ./configure CC="gcc -arch i386 -arch x86_64 -arch ppc -arch ppc64" \
+ CXX="g++ -arch i386 -arch x86_64 -arch ppc -arch ppc64" \
+ CPP="gcc -E" CXXCPP="g++ -E"
+
+ This is not guaranteed to produce working output in all cases, you
+may have to build one architecture at a time and combine the results
+using the `lipo' tool if you have problems.
+
+Installation Names
+==================
+
+ By default, `make install' installs the package's commands under
+`/usr/local/bin', include files under `/usr/local/include', etc. You
+can specify an installation prefix other than `/usr/local' by giving
+`configure' the option `--prefix=PREFIX'.
+
+ You can specify separate installation prefixes for
+architecture-specific files and architecture-independent files. If you
+pass the option `--exec-prefix=PREFIX' to `configure', the package uses
+PREFIX as the prefix for installing programs and libraries.
+Documentation and other data files still use the regular prefix.
+
+ In addition, if you use an unusual directory layout you can give
+options like `--bindir=DIR' to specify different values for particular
+kinds of files. Run `configure --help' for a list of the directories
+you can set and what kinds of files go in them.
+
+ If the package supports it, you can cause programs to be installed
+with an extra prefix or suffix on their names by giving `configure' the
+option `--program-prefix=PREFIX' or `--program-suffix=SUFFIX'.
+
+Optional Features
+=================
+
+ Some packages pay attention to `--enable-FEATURE' options to
+`configure', where FEATURE indicates an optional part of the package.
+They may also pay attention to `--with-PACKAGE' options, where PACKAGE
+is something like `gnu-as' or `x' (for the X Window System). The
+`README' should mention any `--enable-' and `--with-' options that the
+package recognizes.
+
+ For packages that use the X Window System, `configure' can usually
+find the X include and library files automatically, but if it doesn't,
+you can use the `configure' options `--x-includes=DIR' and
+`--x-libraries=DIR' to specify their locations.
+
+Particular systems
+==================
+
+ On HP-UX, the default C compiler is not ANSI C compatible. If GNU
+CC is not installed, it is recommended to use the following options in
+order to use an ANSI C compiler:
+
+ ./configure CC="cc -Ae"
+
+and if that doesn't work, install pre-built binaries of GCC for HP-UX.
+
+ On OSF/1 a.k.a. Tru64, some versions of the default C compiler cannot
+parse its `<wchar.h>' header file. The option `-nodtk' can be used as
+a workaround. If GNU CC is not installed, it is therefore recommended
+to try
+
+ ./configure CC="cc"
+
+and if that doesn't work, try
+
+ ./configure CC="cc -nodtk"
+
+Specifying the System Type
+==========================
+
+ There may be some features `configure' cannot figure out
+automatically, but needs to determine by the type of machine the package
+will run on. Usually, assuming the package is built to be run on the
+_same_ architectures, `configure' can figure that out, but if it prints
+a message saying it cannot guess the machine type, give it the
+`--build=TYPE' option. TYPE can either be a short name for the system
+type, such as `sun4', or a canonical name which has the form:
+
+ CPU-COMPANY-SYSTEM
+
+where SYSTEM can have one of these forms:
+
+ OS KERNEL-OS
+
+ See the file `config.sub' for the possible values of each field. If
+`config.sub' isn't included in this package, then this package doesn't
+need to know the machine type.
+
+ If you are _building_ compiler tools for cross-compiling, you should
+use the option `--target=TYPE' to select the type of system they will
+produce code for.
+
+ If you want to _use_ a cross compiler, that generates code for a
+platform different from the build platform, you should specify the
+"host" platform (i.e., that on which the generated programs will
+eventually be run) with `--host=TYPE'.
+
+Sharing Defaults
+================
+
+ If you want to set default values for `configure' scripts to share,
+you can create a site shell script called `config.site' that gives
+default values for variables like `CC', `cache_file', and `prefix'.
+`configure' looks for `PREFIX/share/config.site' if it exists, then
+`PREFIX/etc/config.site' if it exists. Or, you can set the
+`CONFIG_SITE' environment variable to the location of the site script.
+A warning: not all `configure' scripts look for a site script.
+
+Defining Variables
+==================
+
+ Variables not defined in a site shell script can be set in the
+environment passed to `configure'. However, some packages may run
+configure again during the build, and the customized values of these
+variables may be lost. In order to avoid this problem, you should set
+them in the `configure' command line, using `VAR=value'. For example:
+
+ ./configure CC=/usr/local2/bin/gcc
+
+causes the specified `gcc' to be used as the C compiler (unless it is
+overridden in the site shell script).
+
+Unfortunately, this technique does not work for `CONFIG_SHELL' due to
+an Autoconf bug. Until the bug is fixed you can use this workaround:
+
+ CONFIG_SHELL=/bin/bash /bin/bash ./configure CONFIG_SHELL=/bin/bash
+
+`configure' Invocation
+======================
+
+ `configure' recognizes the following options to control how it
+operates.
+
+`--help'
+`-h'
+ Print a summary of all of the options to `configure', and exit.
+
+`--help=short'
+`--help=recursive'
+ Print a summary of the options unique to this package's
+ `configure', and exit. The `short' variant lists options used
+ only in the top level, while the `recursive' variant lists options
+ also present in any nested packages.
+
+`--version'
+`-V'
+ Print the version of Autoconf used to generate the `configure'
+ script, and exit.
+
+`--cache-file=FILE'
+ Enable the cache: use and save the results of the tests in FILE,
+ traditionally `config.cache'. FILE defaults to `/dev/null' to
+ disable caching.
+
+`--config-cache'
+`-C'
+ Alias for `--cache-file=config.cache'.
+
+`--quiet'
+`--silent'
+`-q'
+ Do not print messages saying which checks are being made. To
+ suppress all normal output, redirect it to `/dev/null' (any error
+ messages will still be shown).
+
+`--srcdir=DIR'
+ Look for the package's source code in directory DIR. Usually
+ `configure' can determine that directory automatically.
+
+`--prefix=DIR'
+ Use DIR as the installation prefix. *Note Installation Names::
+ for more details, including other options available for fine-tuning
+ the installation locations.
+
+`--no-create'
+`-n'
+ Run the configure checks, but stop before creating any output
+ files.
+
+`configure' also accepts some other, not widely useful, options. Run
+`configure --help' for more details.

+ Xft
+ X FreeType library
+ Version 2.3.0
+ 2012-03-07
+
+Xft version 2.1 was the first stand alone release of Xft, a library that
+connects X applications with the FreeType font rasterization library. Xft
+uses fontconfig to locate fonts so it has no configuration files.
+
+Version 2.3.0
+
+Subpixel LCD text rendering improvements
+
+Dropped support for versions of freetype2, fontconfig & libXrender that
+pre-dated pkgconfig support.
+
+Raised minimum required versions to freetype2 2.1.6 & fontconfig 2.5.92.
+
+
+Version 2.2.0
+
+Dropped xft-config, now that pkg-config is well established.
+
+Version 2.1.14
+
+Added fake bold support (#1579, Novell #38202/223682).
+
+Version 2.1.13
+
+Fix hashing in 64-bit versions. Register objects with freetype.
+Fix XftDrawRect when Render not supported.
+
+Version 2.1.12
+
+Fix exporting of XftNameUnparse function.
+
+Version 2.1.9
+
+Stop exporting unnecessary symbols.
+
+Version 2.1.7
+
+Change FC_CHARCELL and FC_MONO interpretation. FC_MONO no longer clips
+glyphs to charcell, you must specify FC_CHARCELL for that.
+
+Add support for FT_GlyphSlot_Embolden where it exists (which it usually
+doesn't).
+
+Avoid crashing when using FT_Face objects.
+
+Version 2.1.6
+
+Deal with broken FreeType 2.1.7 BDF/PCF loaders by trying both y_ppem/x_ppem
+and width/height values.
+
+Version 2.1.5
+
+Left some #warnings from testing in the 2.1.4 release. Spin again.
+
+Version 2.1.4
+
+Work with older versions of Fontconfig by using various pattern elements
+only when defined.
+
+Version 2.1.3
+
+Change Freetype includes to new syntax.
+
+Search for nearest bitmap for bitmap-only fonts.
+
+Support fontconfig 2.2 release which doesn't include FC_HINT_STYLE.

+.SH NAME
+ Xft \- X FreeType interface library
+.SH DESCRIPTION
+.B Xft
+is a simple library designed to interface the FreeType rasterizer with the X
+Rendering Extension.
+This manual page barely scratches the surface of this library.
+.SH "HEADER FILE"
+.B #include <X11/Xft/Xft.h>
+.SH CONSTANTS
+.TP
+.B XFT_MAJOR
+is the major version number of
+.BR Xft .
+.TP
+.B XFT_MINOR
+is the minor version number of
+.BR Xft .
+.TP
+.B XFT_REVISION
+is the revision number of
+.BR Xft .
+.TP
+.B XFT_VERSION
+is
+.B XFT_MAJOR
+times 10000 (ten thousand), plus
+.B XFT_MINOR
+times 100, plus
+.BR XFT_REVISION .
+.TP
+.B XftVersion
+is an alias for
+.BR XFT_VERSION .
+.PP
+The following example illustrates how
+.BR Xft 's
+version constants might be used:
+.nf
+ #if (XFT_VERSION >= 20107)
+ (void) puts("Version 2.1.7 or later of the Xft library is in"
