As far as pixman is concerned, I think support for raster operations
would be a useful addition. The way I would do that is to move the
code for the CopyArea() operation (and possibly the other core
operations) from the X server into pixman.

I'm not sure raster operations make sense as part of the cairo API
(since it is fundamentally dealing with colors and not pixel values).
