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)

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
Also fixes some bugs with property exposure that (along with
other things) allowed you to put table cells on a different
layer than their parent table.

Pcbnew can hang for a long time when undoing operations involving
large numbers of board items. This provides an interim workaround
(and replicated the behaviour of the search panel) by only
computing track statistics updates incrementally if the inspector
is displayed.
Partially fixes https://gitlab.com/kicad/code/kicad/-/issues/17561
(if net inspector is not shown)
This behavior is generally undesirable and was only needed
because of past limitations. Now we only split a track
when the user places a via directly on top of it.

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.
