- The default value is 0.01 mm (according to comments and similar to the 3D viewer
settings that uses 0.02 mm)
- The export dialog has now 3 values 1 micron, 0.01mm (default) and 0.1 mm
The 0.1 micron option is removed: it makes no sense for a mechanical tolerance.
Versions specific variables that may point to objects that change
through versions, allowing multiple KiCad versions to operate correctly
(even on MSW) on the same machine.
- Better code and messages.
- Speedup calculations when removing cutouts and holes from main board.
- Do not stop step generation when trying to load a 3D modele having issues.
This adds a test to the recent GetLayerName function, and moves
it to the base.h file for re-use for any code that needs a
layer name.
This test covers the case that caused lp:1824750 [1].

The SEXPR class is a useful general-purpose S-Expression library
class and can (maybe) be used else where. It also should get
test coverage, as even if noone else uses it, it's critical for the
kicad2step exporter.
Also add some test coverage for some kicad2step routines. For now,
they're not useful outside kicad2step, but they are at least a useful
reference for S-Expression parsing.
More recent Kicad_pcb files have quoted layer names (i.e.
strings, not symbols). The importer in K2S doesn't handle that,
so it chokes on elements like (layer "Edge.Cuts").

The addition of very small segments in OCE triggers sliver
removal/cleanup in the BREP generation that can get stuck in a very long
loop during STEP export of boards. These were introduced to ensure
closure of boards with small gaps that were too big for OCE to consider
joined.
Removing the small segments allows STEP export to proceed in a
reasonable time. This also decreases the default minimum gap size that
kicad2step uses to determine curve matching. This prevents mis-matching
small curves

STEP exporter keeps outline contiguous by storing the last point
coordinates and using them as the starting point for the next segment. It
might create a problem for arcs, as one of the arc end points may become
translated (changed to the last outline point), while the remaining
points (center and the other endpoint) are kept original. For large
deltas it renders an arc invalid, as it cannot pass through a modified
endpoint anymore.
To fix this, short segments are added to link the last outline point
with an arc endpoint, but only if the distance between the two is below
a certain threshold. This way the outline is kept contiguous and the arc
end point is unmodified, warranting its correctness.
