cairo-1.12.16-lto-optional.patch
Log:
Fix firefox crash (bug #507478, thanks to Jaak Ristioja and Patrice
Levesque). Make lto optional (but enabled by default because cairo is a
performance-critical library) and check for enough memory for it (bug #467278,
thanks to Alex). Fix build with USE="opengl -X" (bug #483574, thanks to Sergey
Popov).

Subject: clip: Fix handling of special all-clipped cairo_clip_t
_cairo_clip_intersect_box() wasn't checking if it was called with the special,
read-only all-clipped clip and thus could have ended up writing to read-only
memory.
