Nice job Oliver.  This is a great feature and your plan to add keepout
support to footprints is also a good thing.

I tried it out on my MacOS machine and found an issue I think -- after
deleting a keepout, I filled zones again and the fill is still avoiding the
keepout shape after deletion -- not sure what is going on there.

I also saw an issue where the zone didn't fill all the way to the edge of
the keepout for some shapes, not sure what is going on here: (not sure if
this has to do with your changes or not)

Is there any reason we we don't want to support having filled zones support
multiple layers as well?  It looks like your code is a step in that
direction if we want to go there.  I have used some commercial packages
that allow you to define a zone shape once, and have it fill on multiple
(selectable) copper layers.  I think this would be a good thing for KiCad
to have.

Best,
Jon
