Yes, I believe it would solve the problem. You can either mail me the code (
[EMAIL PROTECTED]) or, if you commit it to 1.8, tell me the file
name.
Thank you.

You could use a FrameBufferObject-viewport (FBOViewport for short). It's
not a part of 1.8 (it really should be.. hm) but it's been posted on
this list a few times, and I have it available (with some slight
improvements). Anyway, it would allow you to add a viewport that does
not render to the framebuffer, but still uses the same window/gl-context
as everything else. Ideal for any render-to-texture work.
Would it help?
