This isn't technically a libvpx bug, but token partition support was added via 
the addition of the -slices parameter in r25551.
Altref I don't expect in the mainline due to philosophical differences about 
the implementation.

Are the philosophical differences regarding altref in mainline documented 
anywhere (ffmpeg mailing list thread, etc.)?

It would be fantastic to have one tool that can create the highest-quality 
.webm and H.264 videos given just about any input. ffmpeg *almost* fits the 
bill there (there are a few x264 options still not supported I think, and 
obviously alt-ref support in VP8 would be required to generate the best quality 
.webm output).

Any missing codec features will be added by patches hosted by this project [1]. 
In general and where appropriate we will continue to send these upstream.
