New version attached.  Offscreen pixmaps should actually work now.

I'm pretty convinced now that upload/download (and Xv accel, for that matter) 
will require a DRM, so I'm not going to worry about implementing them by the 
time I check this in.  I'm still seeing some corruption on Copy ops where I 
get blue or yellow trails, think I'm just off by one on setting width or 
height or whatever.  The XAA code experienced this too sometimes so I'm not 
really considering it a regression, but I still want it fixed.

Composite is being difficult, and slightly hard to debug since all the blends 
go offscreen first.  I'll probably try reimplementing Solid through the 3d 
engine to figure out how setup should really work.

DGA is disabled when EXA is enabled, because I'm a spiteful bastard and DGA is
