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.

58cf74e0c0 0025945: Make stable checking of shape global properties in tests
- Added function checkprops, set default tolerance parameter to 1.0e-4
- Using "area" instead of "square".
- Options "-equal\notequal" isn't used together with "-s" in blend and offset test cases.
- Correct regressions/differences/improvements and CPU problem (set props tolerance to 0.1)
- Corrected test cases to use checkprops proc.
- Correct image difference
- Updated TODOs in test cases.
- Updated test cases to get correct images of result shape

905522eef8 0025880: fuzzy booleans with multiple tools
New features:
class BOPTools_AlgoTools2D
method:
 Standard_Integer BOPTools_AlgoTools2D::AttachExistingPCurve
   (const TopoDS_Edge& aEold,
    const TopoDS_Edge& aEnew,
    const TopoDS_Face& aF,
    const Handle(IntTools_Context)& aCtx)
has been added.

Purpose:
  To attach P-Curve on surface of the face <aF>  from the edge <aEold>
   to the edge <aEnew>
   It returns 0 in case of success.

Changes:
1. class BOPTools_AlgoTools
method:
 Standard_Boolean BOPTools_AlgoTools::IsSplitToReverse
  (const TopoDS_Face& theFSp,
   const TopoDS_Face& theFSr,
   Handle(IntTools_Context)& theContext)

The condition for a point on the surface of a face has been changed.

2. class BOPAlgo_PaveFiller
method:
 void BOPAlgo_PaveFiller::MakePCurves()

The treatment of E/E common bocks has been changed
to use mechanism of attacment P-Curves [ I.1 ]

Test case for issue CR25880
