I drew the two webp files in Photoshop and saved them using the "Save a Copy..." dialog, with ICC profile and all other boxes checked. (I also tried saving with all the boxes unchecked, but it still wrote an extended webp instead of a basic file.) The lossless file exposed a bug: I didn't handle chunk padding correctly before this patch.
