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)
pixman (0.9.3 - 0c80a0cd84f30616563cef5910df9deb4f8ed687)
glitz 0.5.2 (cvs - 2006-01-10)
***** NOTE FOR VISUAL C++ 6.0 *****
VC6 is not supported. Please upgrade to VC8.
==== 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.
