Markers in the viewers

Hi rooters,

Trying to draw my hits, tracks and vertex what is essentualy combination 
of TPolyLine3D and TPolyMarker3D I made the  following observations about 
X3D and OpenGL viewers.
Are there correct or not?

 If I have TPolyMarker3D on the picture 

   - the marker style do not correlate to the declared one: 
     OpenGL alwais draw the square dot, X3D alwais draw the cross sign.

   - the marker size on the OpenGL correlate to the declared one,
     on X3D - not at all

So the only solution that I found to have some consistency on all 3 
displays (usual canvas, OpenGL and X3D) is to use TMarker3DBox.
Are there any different approach?

Conserned TMarker3DBox - why this object is not "rotateable" - it do not 
propose the "rotation" prompt on the usual view?

In general it seems that both X3D and OpenGL interfaces are fare from the 
good shape (colors on the X3D, perspective view on OpenGL etc.).

Are there any plans to improve it?

Best regards 
Valeri
