When I get back to work on tuesday I'll have another look at it and maybe post
the code. (I've been mixing this with other work, so I haven't been able to
fully concentrate on it yet. I'd like to do so first before taking anymore of
you guys' time. :)
Here is my code. Is there anything obvious you can spot?
All my viewports are sized (0,0,1,1), so I assume that in this code.
