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.
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.
Added new parameter for checking whether the plane and cylinder are parallel - the height of the cylinder.
This parameter is needed for the cases when angle between AXIS and plane's normal is very close to PI,
but the "height" is big enough that point, translated from intersection point between cylinder's axis and plane
on the "height" distance in the direction of cylinder's axis, does not belong to the plane.
Such plane and cylinder cannot be considered as parallel.
Add test case for this fix
