cecb900704 video-format: fix pack of 4:2:0 formats 
When packing 4:2:0 formats, we need to take the chroma from the even
lines, for the odd lines we only take luminance.

3f44aaf810 video-chroma: do h subsampling after v subsampling 
We only need to do the horizontal subsampling on 1 line if we do it
after vertical subsampling and we also avoid doing vertical subsampling
on unused pixels.

7888b4f9fa video-converter: keep separate lines with border 
Make separate with a border around them so that we can avoid a memcpy.

3dd059baf3 video-converter: rework the converter to allow more optimizations 
Rework the converter, keep track of the conversion steps by chaining the
cache objects together. We can then walk the chain and decide the
optimal allocation pattern.
Remove the free function, we're not going to need this anytime soon.
Keep track of what output line we're constructing so that we can let the
allocator return a line directly into the target image when possible.
Directly read from the source pixels when possible.

3286320297 video-scaler: fix temp line allocation 
We need to allocate the templine with the amount of pixels we are going
to handle, which we only know for the vertical resampler when we are
asked to resample.

bd6d2b40d1 video-scaler: add support for 16bits formats 
Add scaler functions for 16 bits formats.
Rename the scaler functions so that 16bits versions don't look too
weird.
Remove old unused h_2tap functions
Fix v_ntap functions, it was using 1 tap too little.

e72a01e949 video-converter: Add support for 16 bits formats 
Rework the way we track the current state of the video through the
different conversion phases and use this to make sure we use the right
format and pstride where needed.

2f38f83c08 video-orc: comment out unused function 
A faster version of 4tap horizontal scaling causes segfaults in ORC
presumably because it uses too many registers so disable it to avoid
crashing in the ORC tests.

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.
