The bones aren't animated yet (and I realized I made the mistake of thinking the bone buffer was per-model when it's really per-instance (I think this mistake is in the rest of QF, too)), skin rendering is a mess, need to default vertex attributes that aren't in the model... Still, it's quite satisfying seeing Mr Fixit on screen again :) I wound up moving the pipeline spec in with the rest of the pipelines as the system isn't really ready for separating them.
