Main changes are in "IntWalk_IWalking::TestDeflection(...)" function (IntWalk_IWalking_5.gxx).
Some test cases were corrected according to their new behavior.
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.
1. Checking, if intersection curve is collapsed, is added. (file GeomInt_LineConstructor.cxx)
2. Earlier, intersection line was considered as valid if only mid-point of every interval of this line is into two intersected surfaces (with given tolerance). That's no good because after inserting of new points, old points, which is considered as valid only because they are into beginning or into end of interval (therefore, they was not checked), moved to mid of interval and became invalid. Therefore, checking for first and last points was added. (file GeomInt_LineConstructor.cxx)
3. Intersection line became valid (see bug description) after adding of new additional points into it (file IntPatch_PrmPrmIntersection.cxx). Methods for finding and adding of new points were added. (file IntWalk_PWalking_1.gxx)
Some test cases were changed.
Test cases for issue CR24472
Modifications:
1. The validity of the intersection point between edge and face is checked with sum of the tolerance values of the edge and face.
2. The intersection between toroidal surface and one of the following surfaces: Plane, Cylinder, Sphere, Cone or Torus
is treated as analytical in the following cases:
1) Torus and Plane: a. Axes of the surfaces are parallel;
b. Axes of the surfaces are perpendicular and location of the torus is lying on the plane;
2) Torus and Sphere: The location of the sphere is lying on the line made from toruses axis;
3) Torus and Cone, Cylinder or Torus: The axis of the surfaces are collinear.
In all cases the intersection line(s) is(are) circle(s).
Added test cases bugs/modalg_5/bug24470
The intersection between torus with minor radius more than (or equal to) the major radius and any other surface is considered as parametric.
Eliminated warnings -Wswitch shown by gcc
Eliminated two new warnings about wrong initialization order
Eliminated warnings about unused functions.
A few more ICC warnings (type conversions) fixed
