full screen pan and zoom?

[Larry Bierma]

The October 1988 Software Technical Bulletin has a section summarizing the
SUN color frame buffers.  It states that the CG2 frame buffer has full
screen pan and zoom hardware.  Does anyone know whether the CG3 and CG5
frame buffers have hardware pan and zoom?  If they do how does one tell
the frame buffer to pan and zoom?  I haven't been able to find any
refferences to panning and zooming in TFM.

Thanks,
