[Marco Mattila <marcom99@xxxxxxxxx>]

Hi,

It seems that currently the clearances between zones and pcb edge
segments (and text items and module edge segments on copper layers)
are not something one would expect based on zone clearance settings.
The reason is that, unlike with, e.g., tracks, the minimum zone
thickness is not taken into account when the corresponding items are
converted into polygons. The attached patch fixes that.
