This is a fairness issue. Direct graphics programmers have
had to deal with this since, well, forever with the Z-graphics
buffer. So the good folks at ITTVIS couldn't let the object
graphics programmers get off scott free. They figured
mental anguish should be the right of *all* IDL programmers.

Cheers,
