There will be a 2nd "migration" file, hence the rename.

I needed the definition earlier, and it was easier than doing an extra typedef.

I wanted to argue the interface changes first. In short it will be a
migration scheme on top of driver pixmaps. This is because things like
trapezoids should be done on system ram. The only major difference to
"end users" will be that this will also handle the frontbuffer
"migration". I'm expecting to perform better than a wfb based driver
