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)
When exporting STEP model, warn the user if one of their footprints has
a non-unity scaled model as this compromises the integrity of the STEP
export.

Makes model substitution (VRML->STEP in STEP Export) optional. This can
prevent nasty surprises where the user doesn't see/can't affect the
outcome
Also, when substituting models, do not maintain scale factor. So a VRML
model with non-unity scaling will not be export as a STEP file (of the
same name) with non-unity scaling. This is the first step to address

The same logic block to resolve possible symlinks exists in 5 different
places now. This change moves this duplicated code to a static member
function of WX_FILENAME instead.
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

This is a bit of a hacky solution but in theory should work ok.
There was discussion of bringing in FindPython3 from upstream
CMake, which we could also do if someone is motivated...
