0026348: Visualization, TKOpenGl - eliminate invalid NULL checks for transformation matrix

Browse Source 
Graphic3d_CStructure::Transformation - use Graphic3d_Mat4 instead of plain arrays.
Drop duplicating field OpenGl_Structure::myTransformation (copy of Graphic3d_CStructure::Transformation).
Drop unused property Graphic3d_CStructure::Composition and Graphic3d_Structure::Composition().
