NAME
     glutExtensionSupported -- Determine if an OpenGL extension is available.

LIBRARY
     OpenGLUT - opengl

SYNOPSIS
     #include <openglut.h>

     int
     glutExtensionSupported(const char *extension);

PARAMETERS
      extension     A string-name of an extension.

DESCRIPTION
     Returns 0 if OpenGLUT cannot determine that the requested extension is definitely present.  Only checks extensions from glGetString().

TODO
     Wouldn't this be simpler and clearer if we used strtok()?

     Consider an ogWarning() if there is no current rendering context.

     This is an ugly bit of code with 3 return statements, one of which is never reached.

SEE ALSO
     glGetString(3)
