The GL module incapsulates ROOT's interface to the OpenGL rendering
engine and provides the following functionality:

<ul>

  <li> management of system-resources;

  <li> frequently used utility classes;

  <li> base-classes for shapes, scenes and viewers;

  <li> concrete implementations of shapes needed by TGeo package;

  <li> concrete implementations of scenes and viewers including the
  GUI components;

  <li> specialized plot-painters for GL rendering of TH2, TH3, TF2 and
  TF3 object as well as parametric surfaces.

</ul>
