/*
  Lens flares are an effect that happens in the
  lens - your eye or a camera lens.  As such, they
  are completely invisible if the light itself is
  not visible - which should mean that if the light
  is culled then so is the lens flare.  This suggests
  that the bsphere center should be at the light point
  and the radius should be tiny.

  However, if you have a multi-facetted display,
  pretending to be a single display rather than
  a lot of separate 'cameras' then you may want to
  set the SSGA_CONTINUOUS_DISPLAY_SURFACE flag.

  /*
    Lens flares are best generated in eye-space (because they actually
    occur inside the lens of your eye).  Hence we call 'update' with
    the current modelview matrix - it generates the geometry in eye-space -
    which means that we have to render it with the identity matrix on the
    stack.
