Git commit 71772963359553c2da8d0891d6e179e03f0cd4e5 by Alex Merry.
Committed on 19/01/2014 at 11:23.
Pushed by alexmerry into branch 'master'.

Import the WebP image I/O code from kde-runtime

The plugin export mechanism has been patched up (including the addition
of the JSON file), and the FindWebP.cmake file is new.

Writing is currently disabled, as it produces broken images.

Autotests are generated using the cwebp and dwebp utilities distributed
with the libwebp reference library.
