1) Fixed crack between the trimmed object triangles and the triangles
closing the cut (newly triangulated) by snapping the existing vertices
on cutting plane to coord_t scaled coordinates. Such snapping is
needed for vertices close to zero where float has a higher absolute
accuracy than coord_t.
2) Improved accuracy of triangle cutting by calculating the cut contour with doubles.
3) Improved accuracy of triangle cutting by implementing rounding to coord_t instead of floor.
1) Removed virtual methods. There was not really need for them.
2) Some of the virtual methods were using conversion to Lines, which
was unnecessary and expensive.
3) Removed some nearest element search methods from Point.
Some files have whitespace changes that make resolving conflicts difficult.

removal of artificial extension at the ends of the curve
removal of observation points normalization
added clamping of parameter index which compensates for under-represented spline segments
added parameter for level of freedom at the ends of the curve
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.
circular, convex, concave) and performs efficient collision detection agains these build
volumes. As of now, collision detection is performed against a convex
hull of a concave build volume for efficency.
GCodeProcessor::Result renamed out of GCodeProcessor to GCodeProcessorResult,
so it could be forward declared.
Plater newly exports BuildVolume, not Bed3D. Bed3D is a rendering class,
while BuildVolume is a purely geometric class.
Reduced usage of global wxGetApp, the Bed3D is passed as a parameter
to View3D/Preview/GLCanvas.
Convex hull code was extracted from Geometry.cpp/hpp to Geometry/ConvexHulll.cpp,hpp.
New test inside_convex_polygon().
New efficent point inside polygon test: Decompose convex hull
to bottom / top parts and use the decomposition to detect point inside
a convex polygon in O(log n). decompose_convex_polygon_top_bottom(),
inside_convex_polygon().
New Circle constructing functions: circle_ransac() and circle_taubin_newton().
New polygon_is_convex() test with unit tests.
Fixed some old support and infill issues.
Fixes support problem #4295
Fixes Parts of interface layer extends beyond supports and cannot be printed
Fixes support missing under horizontal overhang #6058
Fixes Slicer double-traces small sections of Rectilinear Supports, causes
Fixes plastic buildup and nozzle crashes #4951
Fixes Add "Angle Interface layers" #2969
Working contour offsetting,
skeleton_edges_rough() to detect "important" skeleton edges.
Radius of an inscribed circle along the "important" skeleton edges
changes slowly, therefore these "important" skeleton edges signify
oblong regions possibly needing a gap fill.
