 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!).
