enabled.
- This is simpler--two fewer entry points, and a trivial decode path.
- Puts the mechanics of frame skipping in the decoder's control. Previously,
all we did was skip conversion and texture updates. Now, the decoder
can be smarter: skip B-frames, or skip to a keyframe.
- This allows for faster decodes, using slice-based conversion: YUV conversion
can be done at the same time as decoding.
