32e849ebc9 0028486: Fuse of several solids fails due to presence of common zones between faces
1. Exception in intersection of two analytical faces has been fixed by adding a simple check on number of vertices
in the resulting analytical curve;

2. Projection of the Circle on the Cone now checks if the Circle's normal direction is parallel to the Cone direction.
If it is not, the different, more advanced, algorithm will be used for projection - ProjLib_ComputeApprox;

3. Intersection of the Edge with the Face (IntTools_EdgeFace algorithm) in QuickCoincidenceCheck mode has been fixed to
avoid the checking of the type of the intersection result if the coincidence check gives the positive result;

4. All common IN edges of the intersecting faces has been added for intersection with section edges to avoid self-intersection in the result;

5. Post treatment of the section edges in Boolean operations has been improved with the new stage which treats the possible
common zones, not detected by the intersection algorithm, between faces by intersecting each section edge with all faces,
not participated in its creation, and in case of coincidence putting it as IN edge into FaceInfo structure of the face.
The new function has been implemented for that - BOPAlgo_PaveFiller::PutSEInOtherFaces().

6. Checking for the SameDomain splits of faces in Boolean Operations has been modified to process the pairs of faces in
which both the section curves and common zones are present.

7. Adjustment of the test case boolean gdml_private ZH3 as improvement.

8. Test cases for the issue.

9. Test cases for the parent issue - 0026789.

370101f340 0028491: Incomplete section curve
The main idea of the fix is to forbid check if intersection curve lies in the some face (with input tolerance) if we have 2D-intersection curve on this face (we consider that necessary tolerance has been computed in intersection algorithm honestly). If we do not have 2D-curve on this face then we need check as before.

New algorithm is implemented in IntTools_Context::IsValidBlockForFaces(...) method.

18c066908f 0027182: Wrong result of General Fuse operation for two spheres
1. The static method Standard_Real MinStep3D(...) in the class BOPTools_AlgoTools is
now checks if the computed 3D step is too big (relatively UV range of the faces)
for any of the faces.

2. The method PointInFace(...) of the class BOPTools_AlgoTools3D has been redesigned.
The new PointInFace(...) methods have been implemented to add possibility for looking the point
inside the face in necessary direction and distance from the edge of the face.
Note: old implementation is also functional.

3. Make methods for finding points near edges and computing normal directions on faces

4. Test case for the issue.

25dfc507be 0028284: Avoid classification of sub-shapes of arguments of BOPs relatively solids during Intersection phase
1. The methods PerformVZ, PerformEZ, PerformFZ and PerformZZ have been transferred from BOPAlgo_PaveFiller to BOPAlgo_CheckerSI class
to perform intersection of sub-shapes with solids only in self-intersection mode.

2. The checks for solids built from the same (shared) faces have been added into methods building the result of Boolean operations -
BOPAlgo_BOP::BuildRC() and BOPAlgo_BOP::BuildSolid().

3. Since the NonDestructive mode is now natively supported by the BOPAlgo_PaveFiller the methods providing the support of this mode by CheckerSI
(BOPAlgo_CheckerSI::PrepareCopy() and BOPAlgo_CheckerSI::PostTreatCopy()) are not needed and have been removed.

4. The pairs of sub-shapes with interfering bounding boxes are now sorted before real intersection to guarantee the constant order of
intersection of sub-shapes and produce more stable result. The class BOPDS_PassKey has been replaced with simpler class BOPDS_Pair.

5. The class BOPDS_SubIterator has been refactored.

6. Test cases for the issue.

f542b7bbf1 0027252: Implicit-implicit intersection (Cylinder-Plane) loses intersection curve
1. Earlier we could not put any IntPatch_Point to the intersection curve. The fix makes the algorithm of IntPatch_Points searching more precise. It is achieved by redetermination of earlier found vertices with help of minimization the distance between boundary of one intersection argument and another intersection argument (surface).
2. Additional check has been added, if IntPatch_Point adjusted to the domain boundary is true intersection point.
3. Method Contap_ArcFunction::Surface() has been added.
4. Method LastComputedPoint() has been added for IntPatch_ArcFunction and Contap_ArcFunction classes.
5. Correction in FindMaxDistance() method (see IntTools_FaceFace.cxx file) according to pure Golden-ratio minimization algorithm. Earlier this function worked wrong with small searching intervals.

  * C1 is set in addition to G1 conditions if derivatives, orthogonal to the edge on each face, are equal vectors;
  * G2 is set in addition to G1 if the centers of principal curvatures are the same for connected faces in each control points through the edge;
  * C2 is set in addition to C1 and G2 if directions of principal curvatures are equal;
  * CN continuity is set only if both connected faces are based on elementary surfaces (the conditions for this case are similar to C2 continuity).

24542bc056 0028017: Unexpected result of General Fuse operation
Several improvements have been made in BO code to fix the bug:

- Create empty edge-edge interference if intersection is close to an end vertex. This will help to avoid creation of unnecessary edge-face intersections.
- Improve PutPaveOnCurve() method to join nearly located vertices when they are put on the same section curve.
- Add processing of same-domain vertices for section edges in UpdatePaveBlocks() method.
- Improve the method CorrectWires() in order to not increase vertex tolerance if it will cover the major part of an edge.
- Replace vertices of section edges by same-domain equivalents.
- In the algorithm BOPAlgo_WireSplitter, correct angles computation and evaluation, taking into account periodicity.
- Modify PostTreatFF to properly take into account the orientations of coinciding section edges.
- In IntTools_Context::ComputePE, check distance from the point to vertices of the edge if the projection to the curve is failure.

Tests update:
- test offset\faces_type_i\C9 has been updated; now instead of returning bad shape it returns null result.

Notes for porting:
- Modify BopAlgo_PaveFiller so that on output each interference refers to the new vertex that will hit in the result (same-domain of the initial new vertex).
- Make the method BOPDS_DS::Index() returning valid index for new shapes.

New test cases have been added.
Tests cases are updated.
