83f3ca27dc reworked and improved the find_next_seam_in_layer method: 
Now uses find nearby_points with radius to save some computations
if all points are far.
From the nearby points, it finds the nearest and best point, and tries
to use them in this order (preivously only nearest was considered).
This helps to snap the alignment to nearby sharp corners if present.

04d4a0d4f7 when searching for central enforcer (for alignment purposes), find properly the first 
enforced segment. Fixed issue where if the enforced segment was painted over the start/end of the
perimeter, part of the enforced points was not considered.

8c2e6aba79 On MSVC, std::deque degenerates to a list of pointers, which defeats 
its purpose of reducing allocator load and memory fragmentation.
https://github.com/microsoft/STL/issues/147#issuecomment-1090148740
Slic3r::deque<> compiles to boost::container::deque<> on Windows,
to std::deque<> on other systems.
SeamPlacer newly uses Slic3r::deque<>.

e95d19b560 WIP, FIXME: Worked around a Perl integration test failure 
in t/perimeters.t, see the comment
FIXME skip the 1st layer in the test 'loops start on concave point if any'

The failure is due to the seam smoothing, which brings the seam too far
away from the external perimeter at the 1st layer, which uses significantly
wider extrusion rate than the other layers. Moving the seam point from
the external perimeter causes an error when projecting the seam point
back to the external perimeter, where the projection lands not exactly
at a corner point, creating a short segment at the end of a polygon loop.

7d02647ebf Removed various Point::ccw() and Point::ccw_angle() methods, they were 
provided for Perl bindings and their semantic was confusing.
Implemented free function angle() to measure angle between two vectors.
Reworked Polygon::convex/concave_points(), changed the meaning of their
angle threshold parameter.
Removed some unused methods from Perl bindings and tests.
Reworked the "wipe inside at the external perimeter" function
after Point::ccw_angle() was removed.
