0023484: Visualization, TKOpenGl - primitive arrays to become the only way to render geometry

Browse Source 
OpenGl_CappingAlgo - draw capping plane using OpenGl_PrimitiveArray.
OpenGl_Trihedron - draw trihedron in wireframe mode using OpenGl_PrimitiveArray.

~OpenGl_Context() - release Delayed resources occured after deletion of Shared resources.

Draw Harness, vzbufftrihedron command - redraw viewer after trihedron definition.
