Historically pixman has been a part of libcairo as an internal library
statically linked in.  However, it is in the process of becomming a
separate library that cairo will eventually depend upon.  Here is
Soren's roadmap posted about a month ago to the cairo list.

   http://lists.freedesktop.org/archives/cairo/2007-April/010371.html

If Xorg is also now depending upon it, then there will probably be a
short term time period when cairo and Xorg use different versions of the
library, but I think the community is already planning to sort this
out.
