 * tune various properties of the image, like:
 * - smooth scaling,
 * - orientation,
 * - aspect ratio during resizes, etc.
 *
 * Image files may be set via memory buffers, image files, EET files
 * with image data or Edje files. On the last case (which is
 * exceptional), most of the properties cited above will @b not be
 * changeable anymore.
