/*----------------------------------------------------------------------------

gls.h - The GLS library provides an API for dynamically loading OpenGL drivers
    on Win32 platforms.  This is necessary because there are some standalone
    3D-only cards that cannot support the official Installable Client Driver
    (ICD) interface for OpenGL on Windows.  These cards, like the 3dfx Voodoo,
    provide "standalone drivers" that are fully OpenGL compliant, but must
    by dynamically linked by the application.

    Applications can use this GLS library to perform this dynamic linking
    without changing any of their core OpenGL code.  By including gls.h
    instead of gl.h (or by making a stub gl.h that simply includes gls.h), an
    application's core OpenGL code (code that calls the gl* functions) will
    simply recompile using the function pointers.  Applications can either
    change their Win32 WGL code to use the GLS API, or they can use the
    glswgl.h file to convert the Win32 WGL code to GLS code implicitly
    using C preprocessor macros.

    See http://www.glsetup.com/dev/gls.htm for more information and to
    report bugs.
