Since the question of "why not just write a cairo backend?" will get
asked, it might be a good idea to put in a link to some of the
discussions of this, such as
http://www.nabble.com/Best-way-organizing-XRender-additions-for-the-X11-pipeline--td14152122.html

Also, references to the classpath work done on a pure-java X11 backend
(which I think supports XRender?) could be useful, for people to
compare.

You will want to pick which way you're going to go with implementing
this (the X11 pipeline extension seems the easiest way, but I don't
know the technical details) before the final draft.

It might be worthwhile listing which drivers have good XRender support
- do opensource drivers for various cards/chipsets have better XRender
support than OpenGL support?

If so, it would be something that gives more support to this idea for
mainstream users, and a fully opensource desktop, not just remote X
users.
