I hadn't thought of this, but it's certainly a valid point.  I can think 
of several solutions, but none which is both efficient and compatible with 
existing mechanisms.

I addressed this in the shadow frame buffer code by special casing 
GetImage to sync contents to the screen before returning the data; we 
can't really do that in this case without a lot of hacks.

Hmm.
