2// GLu header file for the Fast Light Tool Kit (FLTK).

6// You must include this instead of GL/gl.h to get the Microsoft
7// APIENTRY stuff included (from <windows.h>) prior to the OpenGL
8// header files.
9//
10// This file also provides "missing" OpenGL functions, and
11// gl_start() and gl_finish() to allow OpenGL to be used in any window
