Works real fine. Yep. Will be handy for a recent Selections item. But the
last thing I need is for the toolbox to give me a surprise party later. :)


Now , how can I flip all the coordinates in a region, so I can mirror it
across an axis?

I remember 2D Tedd saying he had a method for getting the coordinates out
of a region handle..I can't locate that snippet.

Would be useful to be able to mirror/flip a region, so you can work on a
different view easily, or paint a mirrored area.
