Do dynamic lookup of OpenGL 1.2+ functions on all platforms. Use fallback extension names when the official name is not available, e.g., if glUseProgram is missing try glUseProgramObjectARB instead 2008-02-08 01:43:05 -05:00			`: gl-function-context ( -- context ) glXGetCurrentContext ; inline`
On second thought, no point in being clever with glXGetProcAddress. Just always use glXGetProcAddressARB, which should always be available on any GLX implementation with any extension support 2008-02-08 21:18:44 -05:00			`: gl-function-address ( name -- address ) glXGetProcAddressARB ; inline`
