    video-converter: add fastpath for planar scaling

    Add fastpaths for scaling of planar subsampled formats.

    video-scaler: add support for monochroma formats

    Add support for scaling of images with pstride == 1. This can be used
    to scale individual planes later.
    Rework some of the scaling code to take the pstride as a parameter.

    videoscale: disable chroma and matrix operations

    Ignore chroma subsampling and color matrix transformations like the
    old videoscale used to do. This is to make the performance like it was
    before.
