Thermal scale is currently board-level but we could override it with
some new variables in the pad struct, plus GUI support.

We've talked about this before, I proposed options to allow the user
to change the thermals from X to + or other configurations, including
"none" and "solid".  Again, we'd need another variable in the pad
struct, plus GUI support.

As for the polygons, what we need is a generic poly-cutting routine
that results in more edges (or more polys) and NO clears needed.
Then, we can analyze the resulting polygons for acute angles, islands,
etc.

Unfortunately, we'd need to keep the original polygons too, and do the
cutting and isolating in near-real-time.  Hard job.
