259e98286a replace 'ptr + y * stride' by 'ptr += stride'
This is to prevent potential overflow.

cb215aed5c remove the dependency to stop_watch.[ch] in imageio
Passing the 'verbose' flag to DecodeWebP() wasn't mandated,
and was creating a forced dependency between imageio/ and examples/

Pascal Massimino
ce8733209d Introduce a generic WebPGetImageReader(type) function
Also introduce an always-failing 'reader' for unknown formats.
So we don't have to check reader==NULL, code is more regular.

-> We can get read of specific ReadPNG(), ReadJPEG(), ... declaration and use.

this relies on imageio_util; remove the reference for dwebp as this does
not directly rely on it.
