Snapshots of cairo and glitz for mozilla usage.

We only include the relevant parts of each release (generally, src/*.[ch]),
as we have Makefile.in's that integrate into the Mozilla build system.  For
documentation and similar, please see the official tarballs at
http://www.cairographics.org/.

VERSIONS:

  cairo (1.5.x - c0a7d33ac6c81dd74ee2a9daaa3749a346ef4897)

==== Patches ====

All patches in the cairo tree are surrounded by "MOZILLA_CAIRO_NOT_DEFINED"
(which should obviously not be defined).

Some specific things:

max-font-size.patch: Clamp freetype font size to 1000 to avoid overflow issues

win32-scaled-font-size.patch: Add cairo_win32_font_face_create_for_logfontw_hfont,
allow win32 scaled_fonts to rescale themselves properly to the required CTM
and only use the font_face's hfont if we're sure it's appropriate

win32-logical-font-scale.patch: set CAIRO_WIN32_LOGICAL_FONT_SCALE to 1

win32-no-printer-bitblt.patch: If we need to BitBlt from a DC (to do
fallback), only bother trying if the IS_DISPLAY flag is set -- many
printers lie about their support for BitBlt, and we end up getting
black instead of what we want.

nonfatal-assertions.patch: Make assertions non-fatal

clone-similar-fallback.patch: Implement fallback for clone_similar.
