TPolyMarker3D using TPointSet3DGL for direct OpenGL rendering.

Supports only elementary marker types:

4, 20, 24 : round points, size in pixels;
2, 3, 5 : crosses, size in scene units;
28 : as above, line width 2 pixels;
all other : square points, size in pixels.

Marker-size (from TAttMarker) is multiplied by 5!

An identification of type TObject* can be assigned to each point via SetPointId() method. Set the fOwnIds flag if the ids are owned by the point-set and should be deleted when pointset is cleared or destructed.

Copy-constructor and assignment operator COPIES the ids if the are not owned and CLONES them if they are owned.

The ids are not streamed.
