763057a1a2 Path: Fix 'NoneType' argument error in '_stepTransitionCmds()' 
The 'p1' argument is passed in as 'None' on occasion.  This fix cancels the efficient transition between the two points.  3D Surface is and experimental op, and therefore this fix needs additional user testing with various complex models.

6b3815a766 [path] Implement Ramer-Douglas-Peucker line simplification 
Implement an iterative version of the Ramer-Douglas-Peucker line
simplification algorithm
(https://en.wikipedia.org/wiki/Ramer%E2%80%93Douglas%E2%80%93Peucker_algorithm),
which reduces line complexity to a limited linear deviation from the
original polyline. The ability to reason about linear deflection is the
key improvement over the previous linear implementation.

Worst case complexity is O(n^2), but expected complexity for typical
cases is O(n log n). A potentially faster alternative would be to call
out to libclipper, treating the line as a closed polygon. However, in
practice, performance of this implementation seems good enough. A
complex 3d surface operation optimizes in a few seconds, and reduces
output gcode size from about 220MB with the previous implementation to
10MB.

7c654878d0 Path: Fix for optimizeLinearSegments 
Reduce cumulative error by holding onto the original point in a sequence
of linear optimizations. In testing, this fixes artifacts I have seen on
very finely sampled paths with very gradual curvature.

Further improvements are needed for this optimization, but at least this
change avoids a regression over the status quo.

0c69eebda4 Path: Use _optimizeLinearSegments utility in _planarSinglePassProcess 
Slightly clean up the code by separating linear segment optimization
from gcode generation. While the current optimization is not very
effective once there is any kind of meshing noise, having a single
method performing the optimization will make it easier to tweak
tolerances or strategies.

84113fbd17 Path: More ambitious step-over and break optimizations 
Extend the work from #3496 to allow the safe optimization of more
complex step transitions.

- Use the actual safePDC path for short step transitions and breaks,
  currently up to 2 cutter diameters. This value is chosen to cover
  basically all typical end step-overs, including those with heavy skew.
  Extending this much further (up to the break even point for a retract &
  rapid) will need some careful thinking for multi pass paths.
- Coordinate offset tolerances with per-operation tessellation
  tolerances, to avoid tessellation artifacts messing up paths by
  causing false retracts.  Such retracts can cause entire steps near
  vertical areas to be falsely skipped, which would cause a major
  deviation from the target model.  By considering per-job tolerances, we
  allow users to safely save computational resources by computing roughing
  operations with lower precision, or selectively increase precision for
  finish passes.
- Refine the default tessellation tolerance to GeometryTolerance / 4.
  This makes sure that the job GeometryTolerance is respected by
  operation defaults.

cc84287515 Path: Opt into automatic git newline normalization 
Avoid spurious diffs from inadvertent newline changes by letting git
normalize newlines in the path module as well, just as a list of other
modules including Draft already do.

This effectively standardizes all checked-in code to Unix newlines, but
checkouts might use CRLF if that is the user preference.

4a87209cb5 Path: Safer step over optimization 
- Only apply aggressive optimizations to short horizontal moves within
  cutter diameter. The safe model STL does not accurately reflect stock
  state, so using it for determining long distance move safe heights is
  not safe. There would be a high chance of hitting the stock at rapid
  speeds.

  Thankfully, the vast majority of step-overs tend to be short, so are
  still optimized.
- For short moves, only allow completely lift-free transitions when
  there is (almost) no Z change, and the min safe travel height does not
  rise above the same level.
  Otherwise, lift to the max of end points and min safe travel height
  first, then move horizontally. A future optimization would be to
  directly use the drop scan for transition path generation.
