- do not call ransac when not needed
- decrease number of ransac iterations
- precalculate inverse of transformation matrix
- pass the min error from ransac algorithm, do not calculate it again
Fixes Slicing slows or hangs on "Generating Permiters 20%" cpu load is at 100% #8164
Fixes Slicing hangs on generating perimeters with thing:3565827 (30g) #3259
Implementation of extra perimeters on steep overhangs/flat unsupported parts
Also contains:
Principal components computation over polygon area
New fast bridge direction estimation which minimizes amount of unanchored bridge endpoints
This is the follow-up to 63c66f4f189b6f3d3a3b95ddd158c66ee5166420. Detection of non-planar (degenerated) Voronoi diagrams was rewritten to check if all neighboring edges of the Voronoi vertex are CCW ordered.

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.
