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 - 1.5.6-75-gc621d8d)
  pixman (0.9.x - pixman-0.9.6-34-g787cc57)
  glitz 0.5.2 (cvs - 2006-01-10)

***** NOTE FOR VISUAL C++ 6.0 *****

VC6 is not supported.  Please upgrade to VC8.
