maybe i didn't explain myself clearly.
what i want _is_ possible.
i know it.
i've already worked up a crude version.
i just want a more elegant way.

i can flowchart it quite easily.
1.  write to 640*480 screen.
2.  schlep to gworld.
3.  schlep back to 1024*768 screen.

my crude non-gworld version has step #2 as
2a.   picture on
2b.   set invalrect to whole window
2c.   window fill
2d.   picture off
(i.e., a q-n-d screen dump of the window to a pict& handle)
