c4ea4ca3d1 0032241: Mesh - wrong shading display of thrusections [regression since OCCT 7.4.0]
0032422: Mesh - Weird rendering
0029641: Mesher produce 'bad' result for extruded spline with given deviation coefficient

Added method BRepMesh_NURBSRangeSplitter::getUndefinedInterval() intended to compute checkpoint parameters for those NURBS surfaces which have no intervals at all. In this case number of poles is used to produce artificial regular grid which can be refined further. Add at least one midpoint for surfaces with one interval and only two poles.

Added BRepMesh_ExtrusionRangeSplitter and BRepMesh_UndefinedRangeSplitter derivatives from BRepMesh_NURBSRangeSplitter intended to handle special cases of extrusion surfaces and general surfaces with undefined parameters.

dfb5aebd35 0032982: [Regression to 7.3.0] Mesh - Meshing the shape takes too long and visualization is bad
New formula to calculate number of points along V axis of a cone depending on ratio of its size along V and U.

f1c034f905 0032471: Mesh - Deflection of the triangulation is not recomputed for planar face
Method EstimateDeflection has been added to BRepLib in order to check and update value of deflection provided by Poly_Triangulation;
Introduction of Poly_TriangulationParameters intended to keep info about initial parameters of mesh stored by Poly_Triangulation;
BRepMesh stores user-specified parameters to Poly_Triangulation via Poly_TriangulationParameters;
Prefer initial parameters of mesh generator stored in Poly_Triangulation during check of mesh consistency.
