9c1519c4c5 0027108: GCPnt_TangentialDeflection does not respect linear deflection
Modification of algorithm in order to prevent violation of angular and curvature deflection condition for smooth intervals of curve.
Modification of algorithm for calculation of maximal deflection in command crvtpoints, crvpoints (CR25649)
Elementary bug fixing in algorithm GCPnts_UniformDeflection.gxx
Modification of test cases in order to set new reference parameters of shape triangulations
Some tests:
  bugs modalg_2 bug397
  mesh standard_incmesh C7, V3
  mesh standard_incmesh_parallel C7, V3
  mesh standard_mesh C7, V3
  mesh standard_shading V3
were modified by TODO with reference bug 27226, because some problems in meshing algorithm (package BRepMesh) were discovered when tessellation of edges was changed. These problems cannot be solved by modification of GCPnts_TangentialDeflection algorithm. New issue #27226 was created, see bugtracker for details.

94f71cad33 0024682: Move out B-spline cache from curves and surfaces to dedicated classes BSplCLib_Cache and BSplSLib_Cache
1. B-spline cache was moved into separated classes: BSplCLib_Cache for 2D and 3D curves and BSplSLib_Cache for surfaces.

2. The cache is used now in corresponding adaptor classes (Geom2dAdaptor_Curve, GeomAdaptor_Curve and GeomAdaptor_Surface) when the curve or surface is a B-spline.

3. Algorithms were changed to use adaptors for B-spline calculations instead of curves or surfaces.

4. Precised calculation of derivatives of surface of revolution is implemented for the points of surface placed on the axis of revolution (Geom_SurfaceOfRevolution.cxx)

5. Small modifications are made to adjust algorithms to new behavior of B-spline calculation.

6. Test cases were modified according to the modern behavior.

7. Changes in BOPAlgo_WireSplitter, BOPTools_AlgoTools, BRepLib_CheckCurveOnSurface and ShapeAnalysis_Wire to use adaptors instead of geometric entities

8. Allow Geom2dAdaptor and GeomAdaptor in case of offset curve to use corresponding adaptor for basis curve

Modification of test-cases according to the new behavior.
