kgv b647266461 0027670: Visualization - avoid duplication of structures defining primitive array presentation aspects 
Quantity_ColorRGBA has been introduced as convenient structure holding Vec4 for OpenGL.
Graphic3d_PolygonOffset has been added as replacement for TEL_POFFSET_PARAM.

Duplicating definition of Hatch Styles TEL_HS_*** has been removed;
Aspect_HatchStyle enum now follows values of TEL_HS_*** for compatibility.
TelCullMode enum has been removed.

Aspect_AspectLine has been merged into Graphic3d_AspectLine3d.
Aspect_AspectMarker has been merged into Graphic3d_AspectMarker3d.
Aspect_AspectFillArea has been merged into Graphic3d_AspectFillArea3d.
Graphic3d_CAspectFillArea have been removed.

OpenGl_AspectLine now stores Graphic3d_AspectLine3d as class field.
OpenGl_AspectMarker now stores Graphic3d_AspectMarker3d as class field.
OpenGl_AspectText now stores Graphic3d_AspectText3d as class field.
OpenGl_AspectFace now stores Graphic3d_AspectFillArea3d as class field.

Graphic3d_AspectFillArea3d - back face culling is now enabled by default.
TKOpenGl now relies on Graphic3d_Group::IsClosed() flag to disable face culling.
StdPrs_ShadedShape now does not modify aspect for different culling modes.

Headers InterfaceGraphic_Graphic3d.hxx, InterfaceGraphic_telem.hxx, InterfaceGraphic_tgl_all.hxx
defining obsolete structures CALL_DEF_COLOR, CALL_DEF_POINT,
CALL_DEF_MATERIAL, CALL_DEF_TRANSFORM_PERSISTENCE, TEL_POINT, TEL_COLOUR
have been removed.

Useless and broken test case bugs/vis/buc60821 has been removed.

OpenGl_Workspace::myAspectFaceApplied and myAspectMarkerApplied have been replaced
from OpenGl_AspectFace*/OpenGl_AspectMarker*
to Handle(Graphic3d_AspectFillArea3d)/Handle(Graphic3d_AspectMarker3d).
This eliminates reading from freed memory
(e.g. when OpenGl_AspectFace is allocated on stack like in OpenGl_Trihedron).

OpenGl_PrimitiveArray::drawEdges() - fix drawing non-indexed array from VBO (access violation due to NULL handle).

AIS_Dimension::DrawArrow() - added missing initialization of 3D arrow aspect.
AIS_Manipulator::Compute() now creates dedicated Face Aspect for each axis.
V3d_CircularGrid, V3d_RectangularGrid now create dedicated line aspects with different color.
AIS_InteractiveObject::SetMaterial() - do not modify global ShadingAspect.
