-WebP is an image format that does lossy compression of digital photographic
-images. WebP consists of a codec based on VP8, that Google open-sourced in May
-2010 and a container based on RIFF. Webmasters, web developers and browser
-developers can use WebP to compress, archive and distribute digital images more

 Local changes:
- * Fix cast and initialization warnings
- * Removed from types.h the risky: #ifdef ANSI / #define inline /#endif
  * Removed examples/, documentation and build related files, keeping only
-   the contents of src/.
+   the contents of src/ less mux/ which is unused.
  * Merged COPYING/PATENTS to LICENSE
- * Add BGRX and RGBX variants to the WEBPImportPicture API (needs to be
-   upstreamed to libwebp master).
- * Fix for possible int / size_t overflow in buffer-size calculations
-Upstream cherry-picks:
-7bb6a9c idec: fix internal state corruption
-89cd1bb idec: fix WebPIUpdate failure
+ * Added cpu-features.[hc] from the Android NDK to dsp/.
+ * Revert VP8 encoder changes to avoid WebKit layout test conflicts
