Whoo hooo!

An algorithm that doesn’t cut any conceptual corners (and so should be correct), and is fast as well.

As always, please send in any exceptions.

Cheers,
Jeff.

Do you have a sense of the level of difficulty it would be to implement the previous behavior?  I checked with a couple other packages (Altium, PADS) and this appears to be standard behavior to connect with zone fills between pads of the same net.
