5 The GL module incapsulates ROOT's interface to the OpenGL rendering
6 engine and provides the following functionality:
7 
8  - management of system-resources;
9  - frequently used utility classes;
10  - base-classes for shapes, scenes and viewers;
11  - concrete implementations of shapes needed by TGeo package;
12  - concrete implementations of scenes and viewers including the GUI components;
13  - specialized plot-painters for GL rendering of TH2, TH3, TF2 and TF3 object as well as parametric surfaces.
