If there is a small hole (smaller than the conn width), we can loop
around in a circle checking all points and not move past the mimimum
distance.
To avoid this, if we detect a loop, we exit the substantial checker.
This should return with true because a large hole will return true and
we are only checking to see if there is a minimum amount of copper
between two open areas

We can't assume that the ignored connection exists when trying to set
the junction size. We use int_max for the default instead of 0 so that
later, we don't try to create a minor track with 0 width in loadNets()

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.

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const because it will regenerate the triangulation cache if it is out of
date (using a const_cast, grrr).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

SHAPE_LINE_CHAIN_BASE can include things that are not SHAPE_LINE_CHAIN
like the triangle SHAPE_LINE primitive. To check arcs, we need to avoid
these elements as they do not have the full SHAPE_LINE_CHAIN class
available.

The clearance between two zones could be rather slow. This was in part
to trying to do triangle-triangle collisions between zones when we only
need outline collision and in part to the shape_line_chain collision
routine. The shape_line_chain collisions don't need to recreate
segments on each iteration and should instead create them once and using
this to check all collisions

Between schematic and pcb editors, we want the following actions:
- Single click on ERC/DRC item should show the item in the ERC/DRC
window. But if the window is not visible, it should only update the
status bar
- Double click on ERC/DRC item should show and raid the ERC/DRC window
as well as select the line item

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

This is required as during an undo / redo operation, rebuilding
the previous selection can result in a group / generator being
selected as well as all of their contained items. This prunes
the contained items to remove the possibility of a double-delete.

Avoid issue when a copper layers thickness is 0 (min value is now 1 micrometer)
Fix incorrect rendering of plated graphic items and vias (vertical walls not drawn)
From master branch
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)

(cherry picked from commit c3f6a84d66)
Refactors `SHAPE_POLY_SET::fractureSingle()` to be more efficient, while
not changing the actual algorithm:
* increase cache locality by using contiguous arrays instead of what was
effectively a linked list
* reduce latency and jitter by replacing per-edge allocator calls with
ahead-of-time std::vector reserves
* increase cache efficiency by making the vertex struct smaller
* replace O(n^2) leftmost edge search with O(n log n) std::sort
* sort the polygons instead of the edges
* cut iteration count in half in the remaining O(polygons * edges) part

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
(cherry picked from commit a58e7b37ff)
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.

The behavior of the measure tool is influenced by the
horizontal/vertical/45-degree mode, but the context menu of the measure
tool lacks an option to toggle this mode. In contrast, the drawing
tools are also affected by this mode, and their context menu has the
item to toggle this mode.
