Pixman dependency

[Soeren Sandmann]

Hi,

As a heads up, over the next few days I'll be adding a hard dependency
on the pixman library, which is available from a git repository on

        git.freedesktop.org/git/pixman

Then I am going to move code from the X server into this library. The
code in question is:

        - region code
        - compositing code from fb
        - trapezoid rasterization from fb

I don't expect any API or ABI changes from this as the pixman
datatypes are binary compatible and I'll leave the existing typedef
names in place.
