8d795b5130 0027720: HLRBrep_Algo BSpline missing edges
The algorithm that builds outlines ("silhouettes") makes an outline in 2d parametric space of the surface starting from some previously detected point where normal is orthogonal to direction of view. So, the surface is previously discretized into (m*n) sample points and some of them become starting points for future outlines.

    If the surface has non-uniform parametrization and/or some local extremums of curvature, the outlines can not be built without breaks, so there are several groups of consequent outlines in this case. Unfortunately, it leads to the situation when current number of sample points becomes insufficient to build all the parts of outlines.

    The idea is to detect the "holes" between already constructed parts of outlines and then complete the construction.

New auxiliary draw command for testing of HLR.

Correction according to the remarks.

099f351396 0027739: Visualization, TKV3d - implement individual acceleration data structure for selection of 2D persistent objects
Low-level selection algorithms has been improved to explicitly support 2D
transformation persistent objects. This patch generally touches:

1) SelectMgr_SelectableObjectSet - the lists of objects has been split onto three
subsets (regular, 3d-persistent, 2d-persistent). Each subset has individual BVH
tree. The algorithms are now have more flexibility to update only those trees
that is really required for actual camera state.

2) SelectMgr_ViewerSelector - explicitly supports Eye space selection operations
on BVH tree for 2d-persistent subset. Change of camera position does not
anymore affect acceleration data structure (BVH tree) of 2d-persistent selectable objects.

3) Other classes from SelectMgr have been fine-tuned to provide appropriate API.

Porting notes:

This patch touches very low-level selection classes. If the low-level features were used
the following modifications may need to be considered for porting:

1) Iteration over objects of SelectMgr_SelectableObjectSet should now
be implemented with corresponding Iterator class.

2) SelectMgr_BaseFrustum::ScaleAndTransform and derived classes return
Handle(SelectMgr_BaseFrustum) instead of NCollection_Handle<> type.

3065019c99 0027804: Two breps cause intersections to loop for too long/infinitely
In ProjLib_ComputeApprox algorithm, compute correct parametric tolerance from the input 3D tolerance using surface resolution, in order to pass it to low-level 2D algorithm Approx_FitAndDivide2d (instantiation of the generic class Approx_ComputeCLine). Earlier 3D tolerance was used as parametric tolerance directly, which was a problem for surfaces with too small radius of curvature.

Also, eliminate redundant creation of the object of type AppParCurves_MultiCurve on each iteration in the method Approx_ComputeCLine::Compute.

The post treatment of the Edge/Edge intersections has been improved. Namely:
a. Making the procedure of sharing Edge/Edge intersection vertices consistent with intersection algorithm by enlarging bounding box of each vertex on half of Precision::Confusion();
b. Algorithm of computation of vertex tolerance (in order to cover tangent zone between Edges) has been changed for Line/Circle cases.

8b1e055f0b 0027781: [Regression to 6.9.0] Exception in ShapeFix_Shape algorithm with option FixSmallAreaWireMode
The matter was that during checking wires of a shape for small area, non-outer wires were checked with constructing a new face with BRepBuilderAPI_MakeFace. If a face has location an edge from original face has no pcurve on the constructed face, which leads to exception in BRepGProp::SurfaceProperties. The fix constructs new face using EmptyCopy.

The method ShapeAnalysis_Wire::CheckSmallArea() has been changed so as to check area of the outer wire without hole-wires. API of this method has been changed, as the second argument theIsOuterWire is not needed any more.

The test cases have been updated, below are explanations of changes:

test de iges_2 G7
The fixed version leaves a wire in a face, but the master version considered it small and removed. The master version works wrong. It is because the face built with this wire has negative area, but the code in CheckSmallArea function does not get absolute value before comparing area with the tolerance. The left wire leads to splitting of the face on two, checkshape error in the face, and statshape faulty due to increased number of faces in the second pass.

test de iges_2 G2
The fixed version leaves a wire that is removed in the master version. The cause is the same as in G7 test case. However, here the problematic wire has very big tolerance. So, when the fixed version left it in the shape, the overall maximal tolerance became much greater than in reference data.

test de step_3 E6
In fixed version a really bad small wire is removed from the face, while in master version it is left and produces an error in checkshape report. So, it is an improvement.

5185b1617a 0027780: Face-face intersection produces 2D curve that has reversed derivative at its end
The matter was that with starting point paased into intersector the walking line goes one point outside of the surface domain. Then during purging this extra point is removed from the line but its geometry is used for the last vertex. This makes a set of points invalid for approximation, and as a result we obtain the curve with reversed tangent direction at the end.

The API of the method IntPatch_WLineTool::ComputePurgedWLine has been changed to insert a new Boolean parameter RestrictLine. If this parameter is false than the step of removing of outside points is skipped, and the result line is not distorted. This flag is determined inside IntTools_FaceFace to tell the intersector if it is needed to limit intersection line by surface domain.

Test case has been added.
