f04a9589d4 video: add video blend helper functions to docs 
I don't think those were ever meant to be made public,
but they are, so we might as well document them.

b3ff9c030f video-converter: align offsets to subsampling 
Only apply an offset that is a multiple of the subsampling. To handle
arbitrary offsets in the future, we need to be able to chroma-resample
part of the borders.

a16cd5d2a5 vorbisenc: push an updated segment stop time when we know it 
When encoding, libvorbis will tell us how many samples are encoded
in the buffer it returns. This number may be less than the maximum
of samples in the block, if this is the last packet. In we have no
segment end time, we set it to the end time of that last sample to
tell downstream that the buffer contains less samples.

aa5b5b9085 oggmux: set correct granpos on last page when samples are clipped 
Samples may be clipped at the end, and this is conveyed by a
granulepos that's smaller than it would otherwise be. Use the
segment stop time to detect this, and calculate the right
granulepos.

a93cc13d42 oggdemux: fix last buffer timestamp when samples are clipped 
The end of a stream can be clipped by setting the granulepos of
the last page to a lower value that it otherwise would be.

anyway as it guards against future changes.

49d909dabf video-scaler: add more ORC functions 
Add the old ORC functions for nearest and linear. Label them as Low
quality because they are not as accurate but ORC lacks opcodes to
express this for now.

ca2bd1cc6b video-scaler: rename resampler to video-resampler 
Prefix the resampler with video-. It we would like to reuse the
resampler for audio later, we can copy/move it and deprecate this
one.

549bdd4ece video-converter: rework the generic converter function 
Use a LineCache object to track and process lines between unpack,
upsample, convert, downsample and pack stages. This simplifies the
main core processing function a lot and allows for future additions
easily.

Add support for interlaced formats in chroma up and downsampling.
