Seth Hillbrand 59f99d9a6a Re-add routine to remove duplicate points
The router needs to elimitate duplicate points but keep colinear
segments.  This re-creates the partial routine from the old Simplify()
function

Seth Hillbrand 8260c174e9 Prevent OOB access in polygon split
Check for vertex placement against original size.  Since we are
potentially adding vertices that are out of order with the original
polygon, we only want to check against the first set of vertices when
checking for polygon collision

Seth Hillbrand 553e4a25bf Tidy up some remaining triangulation cases
Found and fixed a few corner cases where triangulation point removal

Seth Hillbrand 06b199fd41 Do not use cache when we modify vertices
When we add vertices to the tesselation routines, we cannot reuse these
without the original vertex points.

It may be possible to copy and modify the vertices from the hint data so
that they are properly positioned but naive attempts (moving based on
first point) did not work, so for now, we disable the hint cache when
the vertex sizes do not match as this prevents OOB access

Seth Hillbrand 6c05f2c67c Move logging message after vertex check
When creating the list, we may have fewer than needed vertices, which

Seth Hillbrand c3f6a84d66 Update triangulation to handle poly-intersection
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)

Seth Hillbrand a58e7b37ff Skip small triangles
The minor triangles cost the same amount of compute time as larger ones
but do not have a material effect on the zone display.  This skips these
minor triangles when earcutting

Seth Hillbrand 7e7fec69f6 Add logging and area check to tesselation
Logging is useful when we find an area that cannot be triangulated.
This will be used to generated test cases.

Skipping minor untesselated areas means that the polygon will still be
considered fully tesselated (and not sent back again and again) even if
the tesselation misses an area less than the configured limit.
Currently, this is 31^2nm.

StefanBruens e07b4ce8e4 Fix triangulationValid check race for zone fill
The m_triangulationValid flag is used in several places without holding
the mutex, thus it should only ever be set when the triangulation is
guaranteed to be valid.

This can either be done by protecting both data and flag by the same
mutex, or updating the flag only after the triangulation has finished.

Also fix the case when the triangulation actually fails, the flag should
not be set in this case.

While at it, simplify the recalculation check. Only if both the
triangulation is valid, and the data hash is unchanged the recalculation
can be skipped - this is typically the case when two threads try to
update the cache concurrently, the second one will block at the mutex,
and will see the valid data after the first thread has finished.

Seth Hillbrand 81cb6d0c3f Fix race condition in zone fill
When checking collisions, the SHAPE_POLY_SET::Collide() routine is not
const because it will regenerate the triangulation cache if it is out of
date (using a const_cast, grrr).  This sidesteps the issue by assigning
a mutex to the triangulation caching

Seth Hillbrand f1dacf7d92 Updated revision of polygon triangulation from 0a67dd3fdd
This maintains the primary goal of ensuring that bad splits do not allow
the triangulation process to continue.  Instead, we boot this back up to
the top-level where we will simplify the polygon before triangulating
again.

Jeff Young 62d959ed0e Don't assume an error location for PAD::GetEffectivePolygon().
While ERROR_INSIDE was good for plotting, 3D generation, etc., it's
not good for generating router hulls.

Also reverts part of the change to always use polygons for PNS::SOLIDs.  A single shape in a SHAPE_COMPOUND will be faster (and
more accurate).

Previously the snap points computed for oval pads didn't get all the

Also adds "extremum points" when the oval isn't exactly H/V.
