Seems I'm running off the end of the octetBuffer after some number of
encoding algo runs.

I don't see any place that decrements _octetBufferStart. It also seems
like the ensureCapacity may not be called in enough places.

I'm pretty tired now so it will likely be Monday before I can dig into
why this one breaks. I'm pretty close to having Xj3D work with FI again.
