Using jit.gl.videoplane as jit.glue

I know there's been some discussion of this before, and I've looked
through the old posts and haven't found the answer I'm looking for.
I'm going straight into jit.gl.videoplane to create 6 equal panes
(using @scale and @position), but I just can't get it right in
jit.window... then when I go to fullscreen, it's completely wrong.
Clearly, I missing something. I can't find any info in the tutorials
or helpfiles about jit.gl.videoplane. There must be a better way of
making this exact than moving them around to make them fit. Just
point me in the right direction. Please.

Also, is this the most efficient way to do it? Things are cramped as
it is in the patch. Any help is awesome.

Thanks so much,
Keith
