Buffer -> Window [message #44428]

I want to copy the contents of an IDLgrBuffer pixel by pixel to an
IDLgrWindow of the same dimensions. What's the easiest way to do this?
I do not want to redraw the graphics tree because redrawing the tree
in the IDLgrWindow will result in a slightly different image due to
differences in resolution between the buffer and window. I can see that
I can get the individual pixels via the IMAGE_DATA property, but there
seems to be no way to load the pixels directly into the IDLgrWindow.

Hmmm... I guess you can do that. I've heard the old mantra about not
being able to mix object graphics and direct graphics so many times, the
thought never occurred to me.
