The schematic net names are fully unique but if we have multiple pads
that are mapped to a NC pin, they need to have unique net names so that
they do not get connected to each other in the ratsnest. This breaks
the schematic parity check as we have modified the netname for some
pads. To work around this, we first maintain the zero-th net without
suffix and then add an additional check in DRC to ensure that we allow
unconnected nets as long as the share a common prefix with the schematic
netname.
Polygon intersections happen against the original outline, not against
the currently remaining polygon. This avoids pathalogical cases
Adds new simplification system to avoid duplicated points
Adds new edge-splitting algorithm to provide additional fall-back
Verifies that polygon cuts do not swap holes for outlines (negative
area)

IPC2581 is a modern production file exchange system. It provides
single-file data output for an entire board including BOM and netlist
information.

We were calculating the same thing in three locations and we missed
adding the clearance from the footprints in, resulting in bad fills and
missed drc errors (see QA addition)
The RegressionZoneFillTests handle issues that are resolved by the zone
filler, so Clipper2 problematic fill belongs there. Otherwise, the
remaining tests should not refill the zones before running DRC because
we expect the DRC to catch errors without needing a refill
Adds QA checks to copper sliver tests. Adds the following checks:
- Dot product between two arms (quickly avoids checks for >90°)
- Checks the sliver is convex (area test)
- Eliminates minor slivers with angles that are approximately 0 and ones
with the opposite side width beneath a configurable level
- Updates Clipper2 to fix a couple of jagged edges on inflate
- Adds simplify during zone fill inflation to limit jaggies

Substantial elements following a divot should be at least as far in each
cardinal direction from the origin point in order to be considered
substantial. This catches cases where the "substantial" element is
actually a straight segment away from the divot

Fractured polygons are always fractured along the x-axis, so when
checking to see if a segment is a fracture point, we check if the y
coordinate is equal. This avoids situations where there are multiple
fracture points between two inflection points
Additionally, we add a second check to ensure we don't hit spurious
blobs (all kinks should be symmetric and therefore be substantial in
each direction)
