Fix burn and dodge operators to match acroread output

Return immediately if the operator is CONJOINT_DST or DISJOINT_DST

These are noops just like plain DST is.

Fix bits_image_fetch_{un}transformed() for 64 bit buffers.

The buffer pointer has to advance twice as far as in the 32 bit case.

Make sure we get all 64 bits in bits_image_fetch_solid_64()

Previously we would only store the first 32 bits.

Only destroy the regions when pixman_compute_composite_region() returns TRUE

Move workaround logic to pixman-bits-image.c.

Instead of computing whether a workaround is needed on every call to
_pixman_run_fast_path(), just cache this information in the image.

Also, when workarounds are needed, clip against the source geometry to
prevent out of bound reads.

Only apply the workaround to source images when out_of_bounds_workaround is set.

Pointed out by Siarhei Siamashka.

Fix scaling-test to work on big endian systems

Convert some leftover instances of Alpha() in pixman-vmx.c.

They were probably missed due to the space before the parens.

Add workarounds for X servers doing out-of-bounds accesses.

Old X servers rely on out-of-bounds accesses when they are asked
to composite with a window as the source. They create a pixman image
pointing to some bogus position in memory, but then they set a clip
region to the position where the actual bits are.

Due to a bug in old versions of pixman, where it would not clip
against the image bounds when a clip region was set, this would
actually work.

The workaround added by this commit is to try and detect whether a
source drawable is actually a window without a client clip set. Such a
window will generally have a clip region that corresponds exactly to
the hierarchy clip in the server, whereas pixmaps will have a clip
region that is an exact match to the drawable.

When we detect such a window, we allow a fast path to run that would
normally be rejected due to the sources not completely subsuming the
composite region.

Fixed X servers should call the new function
pixman_disable_out_of_bounds_workaround() to disable the workaround.

This was reported in bug 22484.

Add a BUILT_SOURCES with pixman-combine{32,64}.{c.h}

Update the CRC value in scaling-test.c.

The changes in pixman behavior justifying this are:

- New clipping rules

- Bug fixes in region code. In particular, when
  pixman_region_init_rects() is called on these two boxes:

{ 2, 6, 7, 6 }
{ 4, 1, 6, 7 }

  it now ignores the first one, which is empty and produces

{ 4, 1, 6, 7 }

  Previously, it would produce:

{ 2, 1, 7, 7 }

  for some reason.

Fix bug in pixman-region.c where empty regions would not be properly initialized.

Also add a couple more tests to region-test.c.

Fix a couple of problems with the tests when HAVE_GTK is not defined.

- Make sure the non-gtk+ test programs are added to noinst_PROGRAMS
  when HAVE_GTK is not set.

- Don't include glib.h in oob-test.c

Merge branch 'naming'

Eliminate boxes with x1 > x2 or y1 > y2 in pixman_region_init_rects().

Add a box with y2 < y1 in region-test.c

Fix up some overeager search-and-replace renamings

Rename num_rects back to numRects.

The name numRects is public API and can't be changed.
