    I disagree with the statement that the sun server needs to use pixrect and
    the hardware rop operations to get good performance.

It does depend somewhat on which Sun hardware you use.  As I recall, on
at least some Sun configurations, the frame buffer is being accessed
through a slow diagnostic port, which makes for inherent performance
problems, not matter how much you speed up the code.  But, I certainly
believe you can do a lot to speed up cfb without resorting to hardware
specifics.
