Essentially adding an artificial dither or quantizer-based noise.  It
looks alot like grain noise in film and hides alot of the DCTs
quantization artifacts.  You can see it in the low-intensity areas on
most DVDs for instance.  The matrix test clip has it.

No, there's no 'grain' option in libTheora at the moment.
