0027932: Improvement of standard attributes usability.
OCAF attributes TDataStd_AsciiString, TDataStd_Integer, TDataStd_Name, TDataStd_Real are extended by possibility to use custom GUID.
Now multiple attributes of any of these types can be placed at the same label using different user-defined GUIDs.
For this new "Set" methods were added into each attribute, which takes this custom GUID as an argument.
Other aspects of management of attributes on labels remain the same.
Version number of persistent OCAF documents is incremented.
However, the attributes are stored in the same way unless non-standard GUID is used for particular attribute.
Previously saved documents are fully supported, but the new documents with this extension used will be non-readable by the previous version of OCAF libraries.

0026917: 3D Offset algorithm produces incorrect result
Extension on the 3D Offset algorithm (Mode="Complete", Join Type = "Intersection")
for colliding cases to add support for new configurations of the shapes.
In the previous approach the result of the offset operation was build from
the offset faces using MakerVolume algorithm, without checking of the validity of these faces.
The new extension is based on this approach, but now the offset faces are being checked
on invalidity and rebuild in case of any. This allows (in case of successful rebuilding) to avoid creation
of the unforeseen parts such as dangling parts, spikes, inverted faces in the result of offset operation.
The main criteria for the validity of the faces is the coincidence of the normal
direction of the offset face with the normal direction of the original face.
Check for removal of invalid faces has been removed as obsolete.

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 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 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.

- 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).

0027431: [Regression to 6.9.1] Huge tolerance obtained during intersection of cylinder and sphere
The root of the problem is incorrect processing of cases when intersection line goes through the apex(es) of sphere. The fix improves this situation. The algorithm is taken from DecomposeResult(...) function (see IntPatch_ImpPrmIntersection.cxx file). Before the fix, faltering steps were done to solve this problem. As result, it worked in some particular cases. Now, its possibilities have been extended significantly.
Following changes have been made in the fix:
1. Class IntPatch_ALineToWLine has been rewritten cardinally. It touches as interfaces of existing methods as adding/removing some methods/fields. Correction touches both cases: going through seam of Cone/Sphere and through pole(s) of sphere. Old interface did not allow making some actions with analytical line (ALine), e.g. splitting it on several Walking-lines (WLine).
2. Restriction-line support has been removed from Implicit-Implicit intersection result (see IntPatch_Intersection::GeomGeomPerfom(...) method). It connects with the fact that the intersection algorithm itself returns precise intersection line in analytical cases (in compare with parametric intersector). Therefore, we do not need in additional (restriction) line.
3. New class IntPatch_SpecialPoints has been added. This class contains methods to add some special points (such as apex of cone, pole of sphere, point on surface boundary etc.) in intersection line (IntPatch_PointLine). It is based on the static functions, which already exist in IntPatch_ImpPrmIntersection.cxx file (these functions have been moved to the new class).
4. Method IntPatch_WLineTool::ExtendTwoWlinesToEachOther(...) has been renamed to IntPatch_WLineTool::ExtendTwoWLines(...). It is connected with changing main idea of the method. Now it allows extending WLine to the surface boundary or to the singular point (if it is possible): cone apex, sphere pole etc. Interface of this method has been corrected, too. At that, old functionality (extending to each other) has been kept. For implementation of this algorithm, new enumeration "IntPatchWT_WLsConnectionType" has been created.
5. Method IntPatch_PointLine::CurvatureRadiusOfIntersLine(...) has been added. See IntPatch_PointLine.hxx for detail information. It allows correct step computing depended on the local curvature of the intersection line. This method uses geometrical properties of intersected surfaces to compute local curvature. Therefore, it can be applied in wide range of cases even if the intersection curve is not represented in explicit form (e.g. in case of param-param-intersection).
6. Method IntSurf::SetPeriod(...) has been created.
7. Additional check has been added in Draft_Modification::Perform() method for better choice of correct fragment of intersection line for processing DRAFT operation.
8. New overload method IntPatch_Point::SetValue() has been added.
