sl2/: standalone slicer (WIP)
...
sfc/slicer.py has troubles with artefacts. It seems that we can do much
better by avoiding the high-level operations and doing all the slicing
"manually".

gp2rml/gp2rml.c (output_paths): use PA when possible; correct speed calculation
...
The mill uses the Z speed for the entire !ZZ movement, whether there
is a Z component or not. We now issue PA instead of !ZZ when moving
horizontally.
Also adapted the speed calculating accordingly.

poly2d/p2d_attrib.c (angle_3): prevent acos() domain errors
...
Rounding errors could push us slightly outside the [-1, 1] range, which
caused acos() to return NaN, which in turn broke p2d_is_cw, and eventually
tripped create_interior_skeleton_and_offset_polygons_with_holes_2.
