I don't know if this separation is strictly necessary.  The Khronos<br>
gl.xml /says/ glBindFragDataLocationEXT is an alias of<br>
glBindFragDataLocation.  There's no published GLX protocol, so there's<br>
nothing that prevents the two from being unaliased in the future.<br>
<br>
I don't feel very strongly about it either way.  Whichever way you<br>
decide to do it, this patch is<br>
