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.
WxString does not allocate space for wide strings needed during
conversion unless the string is explicitly wide. This can cause buffer
over/underflow

(cherry picked from commit 7601a3385f)
Note that the dialogs which have mutliple options were not moved over
as it seems perahps not the right choice to have them save state between
sessions.

Reduce each (Accel & Fallback) to 3 options: Off, Fast, Good. Fast AA
in accelerated canvas uses SMAA with tweaks suggested by David Beinder.
Good AA is super-sampled x2.
Cairo is similarly reduced to Off, Fast, Good, which map to the Cairo
options themselves. Best is removed as it mostly affects text rendering
and not line drawing (as our text is)
Moves the OpenGL AA options to the same Fast/Balanced/HQ options as used
in Fallback. Fast and Balanced are the SMAA options, with decreasing
threshholds and more processing in the balanced version. HQ is
supersampling x2. This takes more memory and may not work for HiDPI
screens with underpowered graphics cards. But it looks the best of the
three options.
The SSx4 option is removed as it added little benefit in either regular
or HiDPI screens

CHANGED: Environment variables defined outside of KiCad will no longer
be saved in the settings file. Paths can be configured via
the Configure Paths dialog and those changes will be saved in
the settings file if the new path is different from the default
and the path variable was not defined in the system environment.
These settings objects could be created in a constructor/destructor
so we should catch the exception since those are noexcept.
Also change the settings trace to match the other kicad traces
as KICAD_SETTINGS
KiCad stores 3D cache files but never gets rid of any of them.
This patch adds a new function called 'CleanCacheDir()'. Any cache
files older than the passed 'number of days' parameter are deleted.

As of ab83c862, the canvas scaling setting is now used on OSX
(before it was ignored). Legacy settings would have this set to 1.0,
which would not automatically scale the canvas and break on Retina
displays. OSX auto detection works well enough in wx 3.0, so we
can use it now.
