1. Divide B-spline curve on sub-intervals (bounded by knots values).

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.
OpenGl_ShaderManager - add predefined GLSL programs for new stereo outputs.
OpenGl_Workspace::Redraw() - do not implicitly disable stereo to allow stereo dump as is.
OpenGl_Caps - add flag swapInterval to control VSync.

Draw Harness, ViewerTest:
- Extend syntax of command vstereo to setup stereo.
- Extend vdump command to allow dump of stereoscopic pair in different formats.
- Extend command vcaps with option vsync.
