I have the same problem, but in a non-performer, standard GL App we have
written. To solve the problem, we had to translate the coordinate system
to the camera(eye) position in double precision manually for all objects prior
to using the graphics engine translate,rotate,draw,etc. commands. SGI could
easily solve this by making their graphics pipe be a 64bit architecture to
match up with their 64 bit R4xxx CPU's.
