I concur.  We should not be violating clearances even in the small
amounts in this bug report.  I realize that this change will create a
diff when existing designs are refilled but it is a more technically
correct solution.  Until (if?) we support arcs for this, I would prefer
to err on the side of caution.  @JP and @Tom, the two of you have
written most of the polygon generation code, is there any reason not to
change this.

Cheers,

Wayne
