Place it right after the input parameter validation. There is no point

sws: separate the calls to scaled vs unscaled conversion
...
Call the scaler function directly rather than through a function
pointer. Drop the now-unused return value from ff_getSwsFunc() and
rename the function to reflect its new role.
This will be useful in the following commits, where it will become
important that the amount of output is different for scaled vs unscaled
case.

swscale : treat float input data as uint 16bpc
...
Currently float are converted to 16b uint in input part
using src depth (32 bits) in hScale16To19 and hScale16to15,
make an invalid shift for the data
So shift the value when using float input
like 16 bpc uint.

PPC64: Add versions of functions in libswscale/input.c optimized for POWER8 VSX SIMD.

This patch addresses Trac ticket #5570 . The optimized functions are in file
libswscale/ppc/input_vsx.c. Each optimized function name is a concatenation of the
corresponding name in libswscale/input.c with suffix _vsx.

A define is left for backwards compat, just in case some person
