System compositor progress

[Robert Ancell]

Hi,

We're now at the point where the system compositor [1] is starting to
work. Any brave souls who want to start playing with this can have a
look at the instructions in the blueprint. Obviously THIS IS HIGHLY
EXPERIMENTAL, so play at your own risk! In saying that, early feedback
is most welcome and anyone who wants to hack on this contact Chris
(RAOF) and I and we can point you at code to play with.
