Snapshots of cairo and libpixman for mozilla usage.  Where possible,
these should be official releases from the cairo project as-is.  If
changes are necessary, they should be documented below and the patch
file included in this directory.

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/.

  cairo 0.5.0
  libpixman 0.1.5
