Pbuffers/ActiveRender2 Cleanup

Please check what the result of this patch is.
It should:

1) restire old upside-down behavior
2) not break anything else
3) if you enable pbuffer_support=true, you should not get GL errors, beacause
your card doesn't advertise the extension, so pbuffer support should be
disabled at runtime.
