OpenGL is designed mainly to accelerate animations - manipulating 3D
objects in real-time - and so the effect on static renders probably
wouldn't be worthwhile. If you're looking to do lower-quality previews
while developing a scene, POV-Ray has the command line switches to do
that already - I think it's +Qx where 0<=x<=9, I used to use it a lot
when running on a 486 but nowadays I use the mosaic preview for quicker
test renders.
