swscale: provide a default scaler if none is set
Conflicts:
libswscale/utils.c
The default is left at bicubic until someone has compared the scalers
properly speed and quality wise.

swscale: provide a default scaler if none is set
...
Lanczos for general case, sinc for upscaling, Gaussian for
downscaling. According to current literature these scalers
should be the best quality-wise algorithms for each case.

This allows specifying more dither algorithms without using up flags and

Note, improving the logic of the checks is left to subsequent
