It was down for me as well, but now it seems to be working fine.

Yes that sounds like a reasonable thing to do. Keeping EGL in mind is
more a future-proofing measure because it gives us a great deal of
platform independence and since the Khronos group says it's the future,
why shouldn't we listen ;-) Unless I'm missing something, the only
places where we would need to differentiate between WGL/GLX/EGL would be
context creation and *MakeCurrent(), anyways. Supporting both OpenGL and
GLES is probably the bigger challenge…
