yeah, I think all we need to do is actually build the gles2 backend.
But it has been a while since I checked (and not really a cogl expert,
and all that).  I just remember that for freedreno I had to use GL and
implement some emulation for GL primitives that the hw does not
support directly, particularly quads needed to be emultated as tri's +
index buffer.
