9f88d1ba02 0028165: Improve performance of Boolean Operations
1. Unification of the usage of the BRepAdaptor_Surface in Boolean Operations algorithm.
For each face when it is necessary the Adaptor is initialized only once and stored in Context.

For that purpose the new IntTools_Context::SurfaceAdaptor(const TopoDS_Face&) method has been implemented.

To provide possibility to take the Adaptor from the context, the context has been added as
a parameter in following methods:
BOPTools_AlgoTools::MakePCurve()
BOPTools_AlgoTools::Sence()
BOPTools_AlgoTools2D::BuildPCurveForEdgeOnFace()
BOPTools_AlgoTools2D::PointOnSurface
BOPTools_AlgoTools2D::CurveOnSurface
BOPTools_AlgoTools2D::AdjustPCurveOnFace
BOPTools_AlgoTools2D::Make2D
BOPTools_AlgoTools2D::MakePCurveOnFace
BOPTools_AlgoTools3D::GetNormalToFaceOnEdge

It is also possible now to pass the context into BOPAlgo_WireSplitter algorithm.

Also, the new IntTools_Context::UVBounds(const TopoDS_Face&) method
has been implemented to get the UV bounds of a face.

2. Additional improvement is a calculation of reduced intersection range only for the intersection
type VERTEX during computation of Edge/Face interference.

3. The methods IntTools_EdgeFace::Prepare() and IntTools_EdgeFace::FindProjectableRoot()
and the fields IntTools_EdgeFace::myProjectableRanges and IntTools_EdgeFace::myFClass2d
have been removed as obsolete.

4. Test cases for the issue.

0d0481c787 0026738: Make Boolean operations safely treating arguments when running with fuzzy option
When fuzzy option is in force prevent increasing tolerance of input shapes. Instead pass increased by fuzzy value the tolerances of sub-shapes everywhere where it is needed by intersection algorithms.

The following changes in API have been made:

- The methods SetFuzzyValue and FuzzyValue have been moved from the classes BOPAlgo_ArgumentAnalyzer, BOPAlgo_Builder, and BOPAlgo_PaveFiller to the base class BOPAlgo_Algo.
- The public method BOPDS_DS::VerticesOnIn has been renamed to SubShapesOnIn, and the new output parameter theCommonPB has been added.
- In BOPTools_AlgoTools, a new argument "theFuzzyValue" has been added in the methods ComputeVV and AreFacesSameDomain.
- In IntTools_Context, a new argument "theFuzzyValue" has been added in the methods ComputeVE and ComputeVF.
- The methods SetFuzzyValue and FuzzyValue have been added in the classes IntTools_EdgeEdge, IntTools_FaceFace.
- In the class IntTools_EdgeFace, the methods SetTolE, SetTolF, TolE, TolF have been removed, and the methods SetFuzzyValue, FuzzyValue have been added.
- The new argument "theTol" has been added in the method IntTools_WLineTool::DecompositionOfWLine.

Some improvements in algorithms have been made during fighting with regressions:

- Correct initialization of pave blocks for degenerated edges.
- In BOPAlgo_PaveFiller::MakeBlocks(), filter out paves on intersection curve that were put on the curve accidentally due to wide range of E-F intersection vertex.
- In the method IntTools_Tools::ComputeTolerance the margin added to the computed tolerance has been increased up to 0.001%.
- The method BOPAlgo_PaveFiller::PutPaveOnCurve has been corrected in order to use the original vertex tolerance instead of the value increased during putting it on other curves.
- The new method BOPDS_PaveBlock::RemoveExtPave has been added.
- The vertex tolerance computation in BOPTools_AlgoTools::CorrectCurveOnSurface has been improved, taking into account intersection segments between p-curves (to avoid regression on "bugs modalg_6 bug22794").
- Improve IsExistingPaveBlock to make more stable catching of coincidence of common block with section curve (against regression "bugs modalg_4 bug697_2" on Linux).

Test case for the bug has been added.

The following test cases have been updated as improvements:
boolean gdml_private ZH2 ZI7 ZJ7
boolean volumemaker C4

The test case bugs/modalg_4/pro19653 has been corrected to make it stable. See comment inside the script for details.

The test case bugs/modalg_6/bug25880 has been corrected to suppress wrong bfuse commands.

The test bugs/modalg_6/bug26954_3 has been corrected to compare the result with more precise reference value.

The "faulty" TODO in boolean/volumemaker/A8 has been made actual for Linux as well.

//Eliminate compilation error on Linux.

3510db6201 0026619: Tolerances of operands are modified using bop
0026796: The result of General Fuse operation is self-intersecting shape

The fix forces creation of new sub-shapes (vertex, edge) when the tolerance of some sub-shape of an argument is to be increased.

This new behavior is turned off by default. It can be turned on using two ways:
1) Setting 'locking' flag of the arguments.
2) Calling the method SetNonDestructive(Standard_True) of the API classes.

Various bug fixes in the algorithm:
- Compute correct tolerance values for intersections of type Line/Line, Line/Plane, Plane/Plane.
- In case of Line/Plane intersection check if line's vertices lie on the plane.
- Do not allow decreasing of the tolerance value of the Line/Line intersection vertex.
- In IntTools_EdgeEdge, call the method FindParameters with proper 3D tolerance of the curve.
- Force making copy of a degenerated edge if its vertex is touched but no 2D intersection with other curves is found.
- Remove pave blocks both ends of which became referring to the same vertex after vertices substitution.
- Avoid exception in IntTools_Context::IsVertexOnLine if Extrema is not done.
- Reduce tolerance of vertex/edge using actual distances to interfered shapes if it was increased due to line/line, line/plane, or plane/plane small intersection angle.
- Update tolerance of edges to reach all representations in a common block.
- In V-E intersections, check if a vertex hits beyond shrunk range, in such case create V-V interference.
- Do not put a section edge to the result if it becomes to be a micro edge after updating its vertex.
- Correctly make vertices same-domain during the work of MakeBlocks.
- Decrease shrunk range at least on a Precision::Confusion() in addition to vertex tolerance.
- Add Confusion to bounding boxes of new shapes in DS
- Add tolerance Precision::Confusion() to compare distances of touching cases to fix regressions.

TODO marks have been removed from (or modified in) the following test cases (Improvements):
boolean bsection M3 N2 R2
boolean gdml_private B6 C2 C6 G7 I6 F6 J1 J4 M7 N1 N8 N9 O3 O4 O6 O8 O9 P1 P2 P5 Q1 Q3 Q5 S9 T2 U4 U5 U9 ZB5 ZB6 ZC1 ZC5 ZD3 ZD6 ZD7 ZH2 ZH5 ZI2 ZI5 ZI7 ZI9 ZJ3 ZJ4 ZJ7 F8 I6 G1

b4109929d6 0023958: Section of shell by plane is incomplete.
Modifications 1
1. To avoid creation of micro edges in the class BOPAlgo_PaveFiller added two new functions ForceInterfVE and
   ForceInterfVF which updates tolerance of Vertex to make it interfere with Edge and Face accordingly.
2. In the class BOPInt_Tools added new function IsInRange which checks whether two ranges cross each other.
3. In the class BOPTools_AlgoTools added new function IntersectCurves2d which intersects pcurves of the face
   to check it on the self-interference.
4. In the function IntTools_BeanFaceIntersector::FastComputeExactIntersection() the check on the coincidence of the whole
   edge with the face (BOPTools_AlgoTools::IsBlockInOnFace) replaced  with the check on the coincidence of one intermediate point with that face.
5. Test cases bugs modalg_1 bug1255, bug1255_1 has been updated with more correct value of the result.
6. TODO statement has been removed from the test cases boolean bcut_complex B1,B3,B5,C2,C4,C6,C8 as they are correct.

Adding test case for issue CR23958

Modification 2
1. In class BOPAlgo_PaveFiller added new function CheckPlanes(nF1, nF2) that checks whether two planar faces have common or intersecting sub shapes.
If these two faces do not have such sub shapes there is no need to intersect them.
2. In the function BOPAlgo_PaveFiller::MakeBlocks() added block for reducing the tolerance values to the previous state for the vertices
that were put on the section curve (with increasing of its tolerance value) that was rejected by the algorithm.

Modification 3
Back to Extrema_ExtAlgo_Grad algorithm in extrema computations in Boolean Operations algorithm.
