On the long run, what about improving the fill algorithm to be able to
only update affected regions?

e.g. As long as an update cannot split the zone and the update has no
overlap with other zones it should be possible to only recalculate parts
of the zone fill and ignoring the rest.

I know this is not easy, especially to find all possible edge-cases. On
the long run it could be a nice usability improvement for people routing
while showing the zone fill as well as to avoid having fills into tracks
(which caused some production failures in the past)


Regards,
Thomas
