Resize8 - An updated version of the original resizing function

[tormento]

Thanks.

Why you didn't set the chroma default as top-left? Usually that's the one used for AVC/HEVC encoding.

Moreover: is there a way to make it work and output arbitrary bitdepth, such as 10/16/32?

Otherwise I need to put

z_ConvertFormat(resample_filter="spline64",dither_type="error_diffusion",pixel_type="yuv420p16")

before the Resize8 line and, on my slow cpu, it's stealing some cycles instead of having it done internally.
