I was wondering if anyone has been able to do some reasonably
fast animation on a VAXstation II/GPX running VMS.  Just filling
the screen seems to be fairly slow using the UIS routines so 
I may be interested in a GPX device driver.  I've scanned the
VCB02 manual and there seems to be a lot of information
about the logical layout of the video subsystem but not a lot
of information about how to get at all this stuff.

Since this would be my first device driver, I expect to crash the
system several times.  (That's why we get 1-2 user systems, right?)

Any documentation leads, sample programs, names, etc are greatly
appreciated.  This includes any Unix based suggestions that may
stand a chance of being ported to VMS.  Maybe there's something
in the X-windows arena?
