This file should be used by G4 developers and category coordinators
to briefly summarize all major modifications introduced in the code
and keep track of all category-tags.
It DOES NOT substitute the  CVS log-message one should put at every
committal in the CVS repository !

History file for visualization/OpenGL
-------------------------------------

22nd May 2000  John Allison  (opengl-V01-01-00)
- Fixed slow response of 2nd window of OpenGLXm.  Worked around Mesa bug
  by sharing static visuals in G4OpenGLXViewer (Guy Barrand):
    static XVisualInfo* vi_single_buffer;
    static XVisualInfo* vi_double_buffer;
- Removed ChooseVisual from G4OpenGLXmViewer.cc - done in base class
  G4OpenGLXViewer.
- Protected double deletion of window in destructors of G4OpenGLXmViewer
  and G4OpenGLXViewer (Guy Barrand).
- Changed requested bits per colour to r,g,b = 1,1,1 in G4OpenGLViewer.cc.
- Corrected order of CreateMainWindow() and InitializeGLView() in X*Viewer
  constructors.
