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.

Adjusting some test cases according to their new behavior.
Creation of new test cases.
----------------------------------------------------------------------------------------------------------------------------
Some explanation of new behavior of some test cases:
1. Regressions:
a) blend simple X4
The problem is described in the issue #0026740. According to this description, the result on the current MASTER seems to be wrong indeed.
b) boolean bcommon_complex C7 and boolean bcut_complex Q1
These test case use same shapes with different Boolean operation (COMMON and CUT). They are already BAD (on the MASTER). Now, some sub-shapes have become not-shared, simply. In my opinion, we shall apply new behavior of these tests.
c) boolean bsection M3
The problem described in the issue #0026777 exists even on the current MASTER.
d) boolean bsection M9
The problem is described in the message http://tracker.dev.opencascade.org/view.php?id=26815#c47546. Here, we have really regression in the picture.
e) boolean bsection N2
The problem is described in issue #0026814.
f) boolean volumemaker G1
The problem is described in issue #26020.
g) bugs modalg_1 bug1255 (and bug1255_1)
The problem is described in issue #26815.
h) bugs modalg_2 bug5805_18, bugs modalg_2 bug5805_42, bugs modalg_2 bug5805_46
The problem is described in issue #25925.
i) bugs modalg_3 bug602
The problem is describes in issue #602.
j) bugs modalg_5 bug24915
The problem is described in the message http://tracker.dev.opencascade.org/view.php?id=25929#c48565. It is not fixed by this issue.
k) bugs modalg_5 bug25838
The main reason is described in issue #0026816.
----------------------------------------------------------------------------
2. Improvements:
a) boolean volumemaker F9
b) bugs modalg_1 bug10160_3
c) bugs modalg_2 bug22557
d) bugs modalg_5 bug25319_1 (_2)
e) draft angle G2

Walking line method extraction into separate class IntTools_WLineTool.
New purging method of walking line had been added. Now point which are out of bounds are deleted.
Minor corrections.
Test case for issue CR26775
Changed the rules for the types of the arguments for different operations:
1. FUSE: All arguments and tools should have the same dimension;
2. CUT: The MAXIMAL dimension of the ARGUMENTS should be less
or equal to the MINIMAL dimension of the TOOLS;
3. CUT21: The MINIMAL dimension of ARGUMENTS should be grater
or equal to the MAXIMAL dimension of the TOOLS;
4. COMMON: The arguments and tools could have any dimensions.
For the arguments of collection type (WIRE, SHELL, COMPSOLID)
the type will be passed into the result of the operation.
The documentation should be updated according to new behavior.
Documentation has been updated.
Implemented suggestions by MSV and some grammar changes.

Correction of test case for issue CR23753
Range of changing of some analytic curves is computed by other methods. It allows computing face's boundaries with more precise.
Tolerance was increased to provide successful work of some algorithms.
Functions BRepOffsetAPI_MiddlePath::Build() and ApproxWithPCurves(...) (file IntTools_FaceFace.cxx) were changed according to new result of algorithm's work.
It is possibly for "outboundaried faces" (see bug#23675) to compute incorrect UV-Bounds, when first parameter is more than last. To avoid it, extended control of computed bounds was added.
Function for fail sameparameter fixing was added to HLRAppli_ReflectLines to avoid creation bad shapes after algorithm's work.
In file ShapeFix_ComposeShell.cxx only text formatting was changed.
Some test cases are changed according to their new behavior.
Added test case bugs/moddata_3/bug23511
class IntAna_QuadQuadGeo
The changes have been done to provide the treatment the cases
when the value of the angle between the planes is small and
the origin of intersection line should be refined.
class IntTools_FaceFace
The changes have been done to provide the treatment of faces
in cases when both are based on planar surfaces.
The UV-bounds have been extended to provide correct solutions
as it has been done for all other cases with plane-based faces.
Added test case bugs/modalg_5/bug24914

- bugs moddata_1 bug13 - Added check for the curve length obtained as a result of intersection
- feat featprism S2 - Corrected square of shape and deleted appropriate TODO
1. Checking, if intersection curve is collapsed, is added. (file GeomInt_LineConstructor.cxx)
2. Earlier, intersection line was considered as valid if only mid-point of every interval of this line is into two intersected surfaces (with given tolerance). That's no good because after inserting of new points, old points, which is considered as valid only because they are into beginning or into end of interval (therefore, they was not checked), moved to mid of interval and became invalid. Therefore, checking for first and last points was added. (file GeomInt_LineConstructor.cxx)
3. Intersection line became valid (see bug description) after adding of new additional points into it (file IntPatch_PrmPrmIntersection.cxx). Methods for finding and adding of new points were added. (file IntWalk_PWalking_1.gxx)
Some test cases were changed.

Small correction of test cases for issue CR24137
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.
