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
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.
Short description:
Works for Symbol and Footprint Editor behind an advanced config option.
For Symbol Editor it is shown for a single item selection (library or symbol).
For Footprint Editor it is shown for a footprint selection.
(fp editor allows a single tree item selection only).
Option stays hidden if current frame has been modified.
Also small fix(?) for similar action to the project manager.
(Call for the Execution has moved inside the file loop.)

This was hard coded at 10IU, which was way too small for pcbnew and
still too small for schematic editor. Instead, we set a default of 50
and allow the user to adjust (smaller for less powerful machines)

This selection improvement feature is hidden behind the advanced
configuration key "PcbSelectionVisibilityRatio". It is turned off (1.0)
by default. Value values are from 0.0 to less that 1.0. From testing,
using a value between 0.1 and 0.3 produces the best results.
This fix uses normal alpha blending described in the link below. The
current design only uses the alpha of the object's color. It could be
improved by doing a full color alpha blending but using the color alpha
alone seems to result in satisfactory results.

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

Previously, almost all connectivity updates were full updates, meaning
that the entire connectivity graph would be rebuilt each time a change
was made to the schematic. This update modifies the update to only
correct the subgraphs that are directly affected by the change.
It uses the existing connection graph to find all affected subgraphs as
well as connections to the changes based on the visible schematic.
These elements are removed from the existing connectivity graph and
marked dirty. They then have a new connectivity graph built only around
their changes. The resulting graph is merged into the original.
Currently, this ability is behind an advanced config flag
`IncrementalConnectivity` while testing.

The spacemouse driver, particularly on Mac, is extremely unstable and
causes crashes even when not being used. This places the interface
behind an advanced config flag to ensure that users can affirmatively
opt-in to the potential for crashes
The pressure relief valve was not useful for common work patterns as it
forced the recalculation on many common actions such as bus expansion.
This caused it to actually feel slower than with the pressure relief
valve off.
For most schematics, realtime is now fast enough to not need the valve
and for those that are extremely complex, removing the valve helps this
run more predictably
The hard coded value was too small for certain calculations. Better to
have a configurable value that is initially set to our error level to
allow for deviations that don't meet the visibility test for spikes.
These have become more apparent with Clipper2
Currently this lives behind the advanced config flag `UseClipper2`.
Enabling this flag will route all Clipper-based calls through the
Clipper2 library instead of the older Clipper. The changes should be
mostly transparent.
Of note, Clipper2 does not utilize the `STRICTLY_SIMPLE` flag because
clipper1 did not actually guarantee a strictly simple polygon.
Currently we ignore this flag but we may decide to run strictly-simple
operations through a second NULL union to simplify the results as much
as possible.
Additionally, the inflation options are slightly different. We cannot
choose the fallback miter. The fallback miter is always square. This
only affects the CHAMFER_ACUTE_CORNERS option in inflate, which does not
appear to be used.
Lastly, we currently utilize the 64-bit integer coordinates for
calculations. This appears to still be faster than 32-bit calculations
in Clipper1 on a modern x86 system. This may not be the case for older
systems, particularly 32-bit systems.
