I noticed in the jit.gl.videoplane help file, the camera is set defualt to z = 4 and x, y to 0. This seems to line up an image place on the videoplane with the original dimensions of the image. But 4 seems like an arbitrary number.

Does anyone know the science behind this magic number 4 for z-axis position of the camera?
