As you can tell I haven't yet tried graphics programming
on Plan 9, apart from the patches to "vt" and "sam" where
somebody else had already done the hard part.
I suppose that window coordinates must also be absolute;
presumably in order to avoid having to intercept data and
add offsets. This fortunately simplifies the subject task.
The only thing missing seems to be writability of /dev/screen.
