I'm having trouble figuring out how scaling works in GL. I have several jit.submatrix objects that i'm trying to display in 2D, and while I can position and have them displayed, the scale is wrong. How do I set the scale in jit.gl.videoplane to not distort them? What does the scale numbers in GL actually reflect?

Ideally, you need to match the ratio of your jit.submatrix matrices to the X and Y scale of your videoplanes. So if your submatrix is 30 x 20, your videoplane scale should be 1.5 1.0 (or any multiple of that, just keep the 3:2 ratio).
