Thanks for your patience, this looks good. Or at least, it looks
better; the code is still kind of wrong, in that it's fetching the
image and _then_ censoring, but since the destination is shared memory
a client could potentially win the race and get some bits out that it
shouldn't. And we're doing this censorship unilaterally, which seems
like excess work if the windows clipping the one we're GetImage'ing
from belong to the same client.

Still, better than before, merged, thanks!
