Say I want to open a port that covers *all* monitors currently active.  How
do I go about this?  If I want to erase the entire GrayRgn, what do I do?

Apparently, OpenPort() only sets up a GrafPort to cover the main screen.
Even calling PaintRgn(GrayRgn) only paints the main screen, not all
monitors.

If I want to (say) black out all monitors currently active, do I have to
walk the GDeviceList and do each one individually?  I'm beginning to think
that's what's required, but I was hoping for a more "elegant" solution,
such as simply painting the GrayRgn (which, as I said, doesn't seem to
work that way).
