Thanks, Monte. I checked it out, but unfortunately none of the options
handle my specific use case in the way I want (which is arguably an
unrealistic expectation, given that I need to have the fill region paint
over some vertices).
I also discovered what may be a bug, or at least a curiosity: after
playing with the nonzero and evenodd options, I tried to restore the
default with:
set the fillrule of the selobj to none
And got:
Message execution error:
Error description: Property: invalid enumeration value
Hint:
Apparently "none" must be quoted. Has it always been that way? I've
seen a couple other cases in recent years where keywords I could have
sworn I'd used unquoted now throw errors until I quote them.
What rule can help us know when keywords must be quoted?
It also occurs to me: if there's no hint, adding "Hint:" looks like a
bug, even though it may not be (doesn't seem to be in this case). Maybe
I'll see if I can get some time to patch that...
