Well, to make this work better, one would need a two-tiered approach:
= use thread-local variables to check if it's a 'special' buffer or not
(like this patch does)
= only do this check on GL APIs that actually modify or read from the frame
buffer (basically stuff like glClear, glEnd, gl(Read|Write)Buffer, ...).
The last is easy to do for 'core' stuff, a bit harder for extensions though.
But anyway, this is mandatory if one day we want to fix the 'windowed'
OpenGL code properly (whatever the method we choose as long as we do not
have the GLX extension exporting the clip list feature to the application).
