Yeah, that was bothering me, and I wasn't sure what was correct. I'll 
update the language to fix this.

That's a pretty heavyweight solution. It also assumes that drivers are 
happy to handle this case, and that GPUs are designed to do this 
efficiently. Neither are my area of expertise, but I suspect neither is 
true.

But it also stems from an incorrect assumption: I don't want to take 
away the display hardware from the Window Manager. In fact, I absolutely 
want the Window Manager involved in this. There are several decisions it 
needs to make and states it needs to manage, including taking the screen 
back if the user wants to alt-tab between applications.

That's a good question. Raster, can we repurpose this, or do you need more?
