Input to YUV Converter
When the input to the main path is not planar 8 bits per component YUV or
8-bit gray then it is converted to planar 8-bit YUV. 2 sets of converters
8-bit gray, it is converted to planar 8-bit YUV. Two sets of converters
exist for this currently: One performs horizontal downscaling by 2
before the conversion, the other leaves the full chroma resolution
before the conversion, the other leaves the full chroma resolution,
but is slightly slower. The scaler will try to preserve full chroma
here when the output uses it. It is possible to force full chroma with

SWS_FULL_CHR_H_INP even for cases where the scaler thinks it is useless.
Horizontal scaler

using specially tuned pshufw instructions.
The remaining scalers are specially-tuned for various filter lengths.
They scale 8-bit unsigned planar data to 16-bit signed planar data.
Future >8 bits per component inputs will need to add a new scaler here
that preserves the input precision.

Vertical scaler and output converter
There is a large number of combined vertical scalers + output converters.
