[theora-dev] spare bits in the theora keyframe header

[Ralph Giles]

Monty,

Derf and I were discussing some theora bitstream improvements. He was 
curious about the spare bits in the keyframe header. There's a keyframe 
type bit which is always DCT_KEY_FRAME aka '0' and two spare bits.

You took out a lot of similar extra bits in the VP3 code. Do you 
remember anything about the motivation for leaving this one in? Given 
the constant, were there plans for wavelet-encoded keyframes?

Anyone else on the list, feel free to speak up. :)
