At least as packaged in f19, it seems to require GL.  I know of people
who have recompiled it, and supposedly have it working to some degree
with GLES.  Not sure if that was the same version as what is in f19,
etc.

Where possible, it would certainly be useful to get more stuff with
GLES support in fedora.
