There is currently no accellerated opengl for cygwin/xfree86. All GLX
calls are rendered by the mesa software renderer. It is on the todo list,
but most developers lack the knowledge of how to integrate it.

There are two sort of opengl libraries. The first does map all opengl
calls to glx and sends them to the x server is waht you want for your
x11 apps. The second (with opengl32) does send the opengl calls to
the hardware accelleration. But then you will not be able to use it with
X11.
