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.
bugs/modalg_4/bug8842_7 - test stable OK (removed TODOs).
bugs/modalg_2/bug453_2 - added ?TODO according to unstable behavior (#25918)
bugs/moddata_1/bug22759 - updated reference data
bugs/vis/bug21091_4 bug21091_5 bug21091_6 bug21091_9 - updated reference data
sewing/tol_100/K1 - added ?TODO according to unstable behavior (test will be removed in #25471)
Unstable test cases were reviewed
Modified test cases using checktrend command
Modified test cases for Linux platform
Modified test cases for Debug mode
Loop back tests for iges and step files with possibility of generation of reference data.
Clean up of test scripts (removal of obsolete code, adding comments, corrected formatting)
two fixes were done (same like bug 23722 and bug 23736)
Cancelling checking for number of warnings
rewrite some test scripts in cause of this and fix 23794
Tolerance checking was weakened.
Fix to check instability on Linux (bug 23822) was added.
TODO messages was added to tests which have different results on Windows and Mandriva2010
Ability to update this TODO in regeneration mode was added.
Add fix to bug 23852
Test groups were recomposed.
'dataexch' was renamed to 'de'.
CPU limit was decreased from 2000 sec. to 1500 sec.
