drawable pixmap rather than directly into the frame buffer. Rewrite
logic in kdoffscreen to make space for new allocations, now deals
correctly with locked areas.
Add support for global screen origins (-origin option), handles both
Xinerama and mouse crossings.
Fix XV enable/disable sequences -- can't use card wrappers as cards have
more than one screen.
Change vesa/fbdev to use new depth-independent rotation shadow update
Fix vesa to allow starting rotation value (again)
Make vesa driver write all colormap changes in one INT10 call
