Pascal Massimino 31b68fe639 cleanup WebPPicture struct and API
* add a real proper pointer for holding memory chunk pointer
  (instead of using y and argb fields)
* polish the doc with details
* add a WebPPictureView() that extract a view from a picture
  without any copy (kind of a fast-crop).
* properly snap the top-left corner for Crop/View. Previously,
  the luma position was not snapped, and was off compared to the chroma.
