README
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. scaled-font-create-deadlock.patch: the "poor man's mutex" that is provided for CAIRO_NO_MUTEX will deadlock if a recursive mutex lock occurs. It's also just a bunch of useless assignments for applications that makes all cairo calls from a single thread. An example of where a deadlock occurs is the cairo_scaled_font_destroy() call from win32_scaled_font_create(), which is a bug, but it illustrates the dangers of that "poor man's mutex". The patch makes all mutex operations do nothing under CAIRO_NO_MUTEX and it fixes the bug in win32_scaled_font_create(). See https://bugzilla.mozilla.org/show_bug.cgi?id=378716
