hi Jeff

This actually also solves this: <https://bugs.launchpad.net/kicad/+bug/1812096>

Den 21. juni 2019 kl. 00.49.55 +02.00, skrev Jeff Young <jeff@xxxxxxxxx>:

> On the master branch in my repo (<https://git.launchpad.net/~jeyjey/kicad/tree/>) I have pushed the new zone algorithm, new solder mask shape generation, and new pad painting (which now is the same as the plot code).
> 
> These changes address:
> 
> <https://bugs.launchpad.net/kicad/+bug/602176> (Anti-pad area should not exclude spokes)
> <https://bugs.launchpad.net/kicad/+bug/1563744> (Zone vs. Soldermask clearance collisions at corners)
> <https://bugs.launchpad.net/kicad/+bug/1782957> (Pcbnew: Zone clearance inconsistency on rounded rectangle pads)
> 
> If folks could test it out on some of their boards that would be great.

It also allows thermal spokes on custom pad shapes (and would allow us to support custom number of spokes if we wished).
