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.

I have also seen in previous posts that the view trihedron in V3d_WIREFRAME mode theWorkspace->SetAspectFace (&anAspectY);
changes colors depending on the state of the view. This behaviour can be easily OpenGl_Utils::Rotate (aModelViewY, -90.0, aScale, 0.0, 0.0);
corrected by altering call_triedron_redraw function in OpenGl_triedron.c of TKOpengl. aContext->WorldViewState.SetCurrent<Standard_Real> (aModelViewY);
The only change needed is to erase glDisable(GL_LIGHTING) that is called before the aContext->ApplyWorldViewMatrix();
Axis name drawing and move this function call just before the initial axis drawing.
Below is the code portion with the modification.I don't know if this is considered to
be a bug but anyway i believe it might help some of you out there.*/
