You've asked an excellent question and I'm surprised it hasn't come up
before. As far as I know, there is no way to do this except as you
suggested using a polygon fill.
What you need is something like a "vpBackgroundFillColor" resource
that would effectively fill in the background that is encompassed by
your viewport (the area defined by the vpXF, vpYF, vpWidthF, and
Unfortunately, this kind of thing requires that you know your viewport
size ahead of time, so that you can fill it before you do any other
plotting. Let me think about this some, and maybe meanwhile, somebody
else has a better solution.
