 GLUT API revision history:

 GLUT_API_VERSION is updated to reflect incompatible GLUT
 API changes (interface changes, semantic changes, deletions,
 or additions).

 GLUT_API_VERSION=1  First public release of GLUT.  11/29/94

 GLUT_API_VERSION=2  Added support for OpenGL/GLX multisampling,
 extension.  Supports new input devices like tablet, dial and button
 box, and Spaceball.  Easy to query OpenGL extensions.

 GLUT_API_VERSION=3  glutMenuStatus added.

 GLUT_API_VERSION=4  glutInitDisplayString, glutWarpPointer,
 glutBitmapLength, glutStrokeLength, glutWindowStatusFunc, dynamic
 video resize subAPI, glutPostWindowRedisplay, glutKeyboardUpFunc,
 glutSpecialUpFunc, glutIgnoreKeyRepeat, glutSetKeyRepeat,
 glutJoystickFunc, glutForceJoystickFunc (NOT FINALIZED!).

 GLUT_API_VERSION=5  glutGetProcAddress (added by BrianP)
