2523aa73cb SmartRGBYUV: fix odd-width problem with pixel replication 
rightmost pixel was missing a copy, which could lead to invalid read.

Also added a lower dimension of 4, below which we use the regular conversion.
This is to prevent corner cases, in addition to not being overkill.

the gcc inline asm is first, this missing check would only have caused

skal
3fc4c539aa Add smart RGB->YUV conversion option -pre 4 
New function: WebPPictureSmartARGBToYUVA()
This implement smart RGB->YUV conversion.

This is rather undocumented for now, and is triggered using '-pre 4'
preprocessing option.

This is slow-ish and use quite some memory, but should be improvable.
This is somehow a usable beta version.
