(I think it's 8192, but in any case, big enough for most current uses)

I'm fairly sure I sad 'could eventually be worked around' as interest in
doing this work has yet to materialize. The 'work around' here is to
create two separate frame buffers, one for each crtc and then create two
separate clip lists for every drawing operation to draw first to one
frame buffer and then to the second. For 2D, this wouldn't be a huge
pain, but for 3D, it would be quite a bit more work.

Icky.
