Note that these are: the X11 versions, newer than 1.1, but based on Mesa,
so they are software rendering.  There is a special test version of the X
server that allows hardware rendering to work here, but it is very alpha.

So, if performance is a major consideration, the Windows native versions
are your only good choice.

Given you have a glut based app, if there are no extraneous X11 calls,
this is your best bet.
