Just on merging to trunk the main area I think of contention is still
the required changed to the fb/ layer,... I think they need to be sent
to the list as split out patches with a why we need these and why we
implemented them this way.... (I know that isn't very X.org but for
changes to places like that I think it is a good idea :-)
