Ah, sorry, missed that you already mentioned a shader in your previous
post, thought you were going to use an FBO in some different way I
didn't know about. I know the basics of 3D graphics programming, just
not the details ;-) Always wanted to invest more time learning those
details, never get around to it unfortunately
