OK, great.

I understand that, and I'm not saying it's a bad thing (actually, that's 
EXACTLY what we need right now ;), but it's not quite consistent with 
the regular OpenGL behavior and therefore somewhat unexpected. Would it 
make sense to have a different entry point for this behavior?

Nonetheless, for the float I'm not sure how to use it. How would I split 
a single float into 4 pieces?

Thanks for your help!
