License statement text corrected; compiler warnings caused by Bison 2.41 disabled for MSVC; a few other compiler warnings on 54-bit Windows eliminated by appropriate type cast
Wrong license statements corrected in several files.
Copyright and license statements added in XSD and GLSL files.
Copyright year updated in some files.
Obsolete documentation files removed from DrawResources.
Elimination of compiler warnings
- ExprIntrp: generated file ExprIntrp.tab.c and related WOK scripts removed from the sources
- ExprIntrp, StepFile: added missing declarations and casts; warnings caused by Flex and Bison code suppressed for MSVC compuler by #pragma
- OSD: dummy #includes added to files containing no code for Windows, to avoid warning on empty file
- PLib: piece of code contained in PLib_ChangeDim.gxx included explicitly in cxx and cleaned
- Other places: some casts added to avoid warnings
1. Approximation of derivative (by Taylor-series and by three points).
2. Some methods (Degree(), GetType(), D0(), D3(), DN()) are added.
3. Getting of subInterval's boundaries.
4. Algorithm for checking if 1st derivative is equal to zero is amended.
5. Cases are controlled when extrema or Project point do not exist.
6. GetNormal() function for gp_Vec2d was added.
7. Computing of Value, D0, D1, D2 and D3 for offset curves was changed.
8. Limitation of tolerance for derivative computing was added.
9. Methods for computing trihedron in singularity point are added.
10. Test tests/bugs/moddata_3/bug23706 is added.
11. Restriction on the LastParameter for visualization of 3-D curves. Calling PlotCurve(...) function for last interval.
12. LProp package is modified for tangent computing in singularity point (LProp_CLProps, LProp_SLProps).
13. Added test cases for issue.
Deleting bad test cases for this fix
