there are numerous references in these forums that FFRender is a reyes renderer.
I useta know how to examine the FFRender code in OS X with a package viewer,
but I forgot how.  maybe if ya read thru the FFRender code, it will say what subdivision
smoothing level (e.g. 4, 6, 8 et al.) it uses for render smoothing.  maybe it only smooths
the quads and skips the triangles.
