Umm - what would you want to achieve with that ?
Kind of "caching" the changes to avoid having to pageflip often ?

Yeah - at least when directbuffers are in use, the tile target allocates
Main memory and blits to the real target in regular intervals.
This would - in that specific case - count as an optimization.
How does *BSD handle such paged buffers ? Like we did in scrdrv 0.7 by
making a virtual linear buffer from it using the MMU ?
