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).
1) Warning in Aspect.cxx couldn't be reproduced
2) Description of changes: added 'return' statements into ReadStep(...) functions of RWStepBasic_* classes.
3) BRepFill_OffsetWire.cxx - removed dead code;
4) IFSelect_WorkSession.cxx - swapped arguments;
5) TopOpeBRep_ShapeIntersector2d.cxx - removed 'brake' statement and changed loop to if-statement because of
void TopOpeBRep_ShapeIntersector2d::FindFFIntersection() function's call features.
6) V2d_RectangularGraphicGrid.cxx - left constants instead of functions beacuse of faster perfomance.
7) Commented unreachable code in files GeomFill_LocationGuide.cxx and TopOpeBRepTool_mkTondgE.cxx
