@ -27,3 +27,8 @@ fbcompose-bandaid.patch: Disable "optimized" code in non-MMX case due to bugs
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-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.
