Hi Martin,

> and it's almost mandatory for making good dice. :)

That's sort of the problem - its use only seems to come up very rarely...

Just in general I'm not crazy about adding in options that only have any use in very rare circumstances, that's pretty much how bloat happens.

I guess though that setback corners are mutually exclusive with "straight corners" and maybe I can replace the "Straight corners" option to instead have a dropdown with Corners = normal, straight, or setback.
