extension. In fact, most extensions are not simply enabled or disabled
with a single switch. For example, the multitexture extension defines a
series of textures, each of which can be individually enabled or disabled and
each has a current set of texture coordinates.</FONT></SPAN></DIV>

extensions are "disabled" and you get you standard OpenGL pipeline. If you
wish to use an extension, look up the documentation for that extension and start
using it (after loading it, of course).</FONT></SPAN></DIV>
