92668da6f2 change default filtering parameters: 
* type is now 'strong'
  * strength is now '60'

These help with gradients and blocking

of similar size, but with better quality.

66c810bc3c add a -yuv option to dwebp (very similar to -pgm) 
It will decode to raw (flat) YUV format, similar to what
cwebp can take as input. Makes the PSNR/SSIM calculation easier.

0aeba52852 Provide an option to build decoder library. 
When the config option '--enable-libwebpdecoder' is specified, the
lean decoder library 'libwebpdecoder' will be created in addition to
libwebp. Also dwebp binary will be linked to libwebpdecoder, if this
config option is specified.

versions < 4.0.0 used uint32 interchangeably, but with 4.0.0 toff_t
became 64-bit and TIFFTAG_EXIFIFD began returning it rather than
TIFF_LONG/uint32.
