Reviewed-by: Michal Privoznik <mprivozn at redhat.com> and pushed. Even
though I still don't understand what good it is to use egl-headless with
accel3d='no'. Can it be used for when I'm passing two video cards? For
instance, one <video/> (primary) and then <hostdev/> (secondary) and I
want the secondary card (which is a physical card, hence more powerful)
to do the rendering?
