Conversion of gp_Quaternion to and from intrinsic Tait-Bryan angles (including gp_YawPitchRoll) is fixed.
Before that fix the sequence of rotation axes was opposite to intended; e.g. gp_YawPitchRoll (equivalent to gp_Intrinsic_ZYX) actually was defining intrinsic rotations around X, then Y, then Z.
Now this is fixed, and rotations are made in correct order.
Comments to gp_EulerSequence enumeration are restored (lost due to CDL extraction).
Test bugs fclasses bug25574 is added to check correctness of Euler sequences, including cases from #25574 and #25946.
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.
