sure, from a quick look seems like it should be backwards compatible..
probably we should set up a git tree on fd.o for kmscube

It does make me realize that I do need to figure out what to do w/ the
atomic/fences branches.. maybe I should just make a legacy branch
which sticks with the legacy APIs for hw that doesn't support atomic
and old kernels.  Otherwise I guess kmscube maybe needs to get split
into more than one file to keep it from being too much of a mess ;-)

btw, interesting that you went the route of an extra plane for
"metadata"..  I have something similar w/ a5xx, and was assuming I'd
just have to go single-plane with well known formula for calculating
offset of color data from aux data, to avoid confusing dri2/dri3 too
badly.
