>Fix:
$ fetch https://hg.mozilla.org/mozilla-central/raw-file/tip/gfx/cairo/xlib-glyph-clip-region.patch
$ sed -i '' 's|[ab]/gfx/cairo/cairo/||' xlib-glyph-clip-region.patch

$ svn add files/patch-src_cairo-xlib-surface.c

mozilla-central/gfx/cairo/README states the bug was fixed in cairo-1.11.3:

  http://cgit.freedesktop.org/cairo/commit/?id=be1ff2f
  http://cgit.freedesktop.org/cairo/commit/?id=b132fae

but reading mozilla's bug 856419 it may actually have reoccured.
