It is undocumented that dragGreyRegion, when it changes the region
passed to it, creates the frame of the region passed to it.  I said
that it was interesting that it isn't possible to create a frame
of a region in any other way.  Others have then asked if you can't
use insetRgn as a primitive to frame a region... well you can create
something like a frame that way, but it isn't a frame.  If you do
this on an oval the frame you get will not be uniformly one pixel
wide... i.e. pouring paint into it will leak, or it will have large
thick lines in it.
  You can't change a bit map into a region either, if you could then
you might use the outline capablity in the font generation machinery.
