Passing the 'verbose' flag to DecodeWebP() wasn't mandated,
and was creating a forced dependency between imageio/ and examples/

For some reason, gcc has hard time inlining this one...
Also optimize predictor #0 and #1 for encoding, so we don't have to
call the generic pointers VP8LPredictors[...]

WebPDecoder.framework replaces WebP.framework as the decode-only
framework.
WebP.framework now includes the full library allowing for use of the
encoder.

...instead of the pointers stored in the array.
Should be faster (inlined) and safer.
Also: suffix explicitly the functions with _SSE2

Before, a first thread could enter VP8LDspInitSSE2, set
VP8LPredictorsAdd to an SSE2 version BEFORE another thread
would do the memcpy from VP8LPredictorsAdd to VP8LPredictorsAdd_C
thus leading to a C version actually being the SSE2 one (which
would then create an infinite recursion in the SSE2 predictors
at execution).

it actually disables the disposal / blending method
and just displays the raw delta values.
Useful for debugging.
