1. Eliminated exception after conversion non-rational B-spline to rational
2. Implemented DRAW command setweight to change weights of B-spline
3. Test cases were added

API of Geom2d_TrimmedCurve is changed according to Geom_TrimmedCurve.
Test-case for issue #24411
Sometimes curve or surface, which is defined as C0, has continuity G1 or above. Offset can be built from these shapes.
Therefore, this extended checking was added into SetBasisCurve and SetBasisSurface methods.
Main changes in function BRepOffset_Tool::ExtentFace(...):
* "return" is added if intersection (in 2D-space) between two edges in a face cannot be found.
Basis curve/surface continuity value found (if G1-checking is OK) is set up as BasisContinuity (see myBasisCurveContinuity and myBasisSurfContinuity members which is returned by GetBasisCurveContinuity and GetBasisSurfContinuity() methods). This fact is used in Geom2dAdaptor and in GeomAdaptor classes.
Possibility is entered, which allows for basis elements of offset curve/surface to avoid of C0-checking.
Test cases were changed according to their new behavior.
Test-cases for issue #25124
Macros ending on "DEB" are replaced by OCCT_DEBUG across OCCT code; new macros described in documentation.
Macros starting with DEB are changed to start with "OCCT_DEBUG_".
Some code cleaned.
Existing method of Cylinder-Cylinder intersection computing is based on finding the analytic line (as a function of one argument) and converting one into the walking-line with set of equidistant (along the line parameter) points.
The main advantage of applied method is using adaptively computed step. Necessary step is computed into every point of the obtained walking-line. At that we receive final walking-line directly (without preliminary analytic line) and we determine moments more precisely, when it should be split (see IntPatch_ImpImpIntersection_4.gxx).
The main disadvantages is bad working this method for non-trimmed cylinders (with infinite bounds), because step value is depend on the boundaries values.
More over, new method always returns walking-line, while intersection result can be an analytic curve (lines, circle, ellipse). That is NO good. Therefore, analytic curve is computed by existing method.
In conclusion, in spite of covering almost all more often meeting cases, new method has limited application. Then we should use the existing old method.
Additionally, method MinMax() is added (see Standard_Real.hxx file). It uses into new algorithm.
Some test cases is changed according to their new behavior.
Test case for issue CR24915 is added.
Into GeometryTest_APICommands.cxx only tabulations were chaged.
"Extending" of isolines (see Geom2dHatch_Hatcher.cxx).
Small correction of test case for issue CR24915.
Redundant keyword 'mutable' removed in CDL files.
In IGESConvGeom_GeomBuilder, unused methods MakeXY() and MakeXYZ() removed.
Method StepAP214_AutoDesignGroupAssignment::Init() replicating same method of the base class is removed as it causes CDL extraction error after above (seemingly irrelevant) changes.
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.
When warnings are enabled, compilers report lots of occurrences
of unused local variables, which makes it harder to find other
meaningful warnings.
This commit does not fix all unused local variables.
Fix new type conversion warning
Code cleaned to avoid MSVC compiler warnings on unused function arguments.
Several useless pieces of code are removed.
Changes in IntTools_EdgeFace.cxx, Blend_Walking_1.gxx, Bnd_BoundSortBox.cxx, ProjLib_ProjectedCurve.cxx are reverted (separated to specific issue for more in-depth analysis).

Changed values for min and max parameter vars;
Got rid of redundant variables' initialization.
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.

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
Add a checking into files Geom_OffsetSurface.cxx, Geom_OffsetCurve.cxx, Geom2d_OffsetCurve.cxx , which try to make continuity of bspline surfaces and curves more than C0 to build offset.
Delete duplicate code and checkings
Prevent change of offset curve / surface when exception is raised due to attempt to set new C0 basis curve / surface
