0028165: Improve performance of Boolean Operations
1. Unification of the usage of the BRepAdaptor_Surface in Boolean Operations algorithm. For each face when it is necessary the Adaptor is initialized only once and stored in Context. For that purpose the new IntTools_Context::SurfaceAdaptor(const TopoDS_Face&) method has been implemented. To provide possibility to take the Adaptor from the context, the context has been added as a parameter in following methods: BOPTools_AlgoTools::MakePCurve() BOPTools_AlgoTools::Sence() BOPTools_AlgoTools2D::BuildPCurveForEdgeOnFace() BOPTools_AlgoTools2D::PointOnSurface BOPTools_AlgoTools2D::CurveOnSurface BOPTools_AlgoTools2D::AdjustPCurveOnFace BOPTools_AlgoTools2D::Make2D BOPTools_AlgoTools2D::MakePCurveOnFace BOPTools_AlgoTools3D::GetNormalToFaceOnEdge It is also possible now to pass the context into BOPAlgo_WireSplitter algorithm. Also, the new IntTools_Context::UVBounds(const TopoDS_Face&) method has been implemented to get the UV bounds of a face. 2. Additional improvement is a calculation of reduced intersection range only for the intersection type VERTEX during computation of Edge/Face interference. 3. The methods IntTools_EdgeFace::Prepare() and IntTools_EdgeFace::FindProjectableRoot() and the fields IntTools_EdgeFace::myProjectableRanges and IntTools_EdgeFace::myFClass2d have been removed as obsolete. 4. Test cases for the issue.
