More about copper zones filled without grid (by polygons)
Currently for eyes and tests only.
now working
thermal reliefs.
texts on copper zones.
To select this feature choose No Grid in zone grid filling.
Work in progress:
currently : not implemented:
Removing insulated copper islands.
trapezoidal pads
