* commit '6b3ff6f91a535d6383f41ca7bdf760165dcb6015':
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.
Merged-by: Michael Niedermayer <michaelni@gmx.at>
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.

Before this commit, sws_init_context() failed with an error if no scaler
was explicitly set.
Defaulting to something reasonable is better behavior.

Previously this would have lead to a memcpy(a,a) which violates the
requirement of non overlapping src and dst.
