OpenGLUT is an open source project to evolve the GLUT API. It uses the FreeGLUT code base as a foundation for extending, enhancing, and refining the library interface. The initial goal is to define and implement OpenGLUT API Version 1.0, which is intended to supercede the GLUT 3.x API. 0.6.3 features Win32 game mode fixes, Win32 sub-window fixes, substantial documentation refinements, Win32 mouse drag refinements, and GLUI compatibility improvements. Some Redbook example programs were added. Cygwin and Mingw32 support were improved. Dev-C++ project files were added. There are some joystick refinements, and a demo program was added. An experimental window stay-on-top mode was added. OpenGLUT Homepage: www.openglut.org
