0022    TGLHistPainter is a proxy class. It inherits TVirtualHistPainter and
0023    overrides its virtual functions, but all actual work is done by :
0024       THistPainter - I name it "default" painter, it's the member of type
0025                      TVirtualHistPainter * and loaded via plugin-manager;
0026       TGLLegoPainter - it draws different legos (lego/lego1/lego2/lego3);
0027       TGLSurfacePainter - supports surfaces (surf/surf1/surf2/surf3/surf4/surf5);
0028       TGLBoxPainter - box option for TH3;
0029       TGLTF3Painter - TF3.
