Well, if you lower POVRays q level, then you can have a lot more speed.
Enough that OpenGL stll probably wouldn't make much difference. But you
do raise an interesting point. What of instead of doing test renders,
you could have a preview window that updated itself everytime it could
parse the source code with out errors. Meaning that whille you type it
isn't updating the preview, but when you stop you get instant feed
back. It could also support realtime texturing, so that you could see
if you had the textures possitioned correctly.
