29263c947e 0031425: Visualization - free Edge has selection sensitivity inconsistent to presentation
BRepTools::Triangulation() has been extended with a new parameter for checking Poly_Polygon3D presense within free Edges.
StdPrs_WFShape::Add() now performs auto-triangulation in the same way as StdPrs_ShadedShape::Add().
StdSelect_BRepSelectionTool::GetEdgeSensitive() now creates Select3D_SensitiveSegment instead of Select3D_SensitiveCurve for tessellated segment.
Select3D_SensitiveSegment default sensitivity factor has been changed to 3 pixels to match Select3D_SensitiveCurve.

Test case bug23625_1, added workaround for out-of-range crash in HLRBRep_PolyAlgo on re-triangulated shape.

fffc249f21 0027531: Modeling Algorithms - Make the algorithm Approx_SameParameter more clear and robust
Approx/Approx_SameParameter.cxx,hxx:
Class Approx_SameParameter refactoring. Logic is changed in many places to unify usage, simplify maintenance.
Method Curve2d() is changed to return Geom2d_Curve instead of Geom2d_BSplineCurve. Corresponding message is added to the upgrade guide.
.lxx file is merged into .hxx.
Tangent computation is extracted into special method.
Comparing number of sample points after CheckSameParameter(...) is added to define cases with projection fails.
Undesirable behavior when curves are not same parameterized is fixed.

Geom2dAdaptor/Geom2dAdaptor.cxx: treatment of offset curve is added

Adaptor3d/Adaptor3d_TopolTool.cxx: minor improvement of performance for BSpline surfaces with huge number of knots

Tests were modified according to new behavior of sameparameter algorithm

936ce1f273 0031199: BRepMesh fails on thin faces
Use real tolerance of a face to define threshold for tolerance of discrete model instead of empirical values based on discrete model itself

8c186dad9b 0025044: BRepMesh tweaks - treatments for degenerated and tiny faces
BRepMesh_ModelHealer - recognize a small face with 1 wire and 2 small edges as a face for refinement.
BRepMesh_DefaultRangeSplinner - reduce tolerance on tiny faces to improve the meshing results.

Added new test cases: bugs mesh bug25044_*.
Existing test cases updated to reflect improvements.

3977d18aca 0030286: Cover polygonal HLR algorithm by regression tests
New folder "hlr" with subfolders "exact_hlr" and "poly_hlr" has been created.
Draw command "vcomputehlr" has been corrected.
QA command "OCC27341" has been deleted as "vcomputehlr" does its job.
