On Linux, this directory is shared between users, so a multi-user
machine needs to let the other users have access to the directory to
create their own lockfiles.
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

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
Currently, new global or local net labels are auto-filled with the
net name if the wire is driven by a global or local label. This
currently happens recursively within SCH_LINE. This fix moves this
to determining the driver from the connectivity graph, and removes
the determination from the SCH_LINE code where it does not belong.

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.
Most of our pointers will share the top 32 or more bits of their pointer
addresses, making cache collisions highly likely. This uses a hash
combiner to mix the bits more effectively
The clearance epsilon should not be used to limit which force elements
we return in the query. Otherwise, we can drag elements into a
DRC-violating space

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)
Fixes https://gitlab.com/kicad/code/kicad/-/issues/17559
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)
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
