 * Scale down the default size of an image.

 * values are 'thumb' or 'thumbnail' for the given thumbnail size or defaults at
 * 128 width and 96 height in pixels. Also supported for the string value is
 * 'medium' and 'full'. The 'full' isn't actually supported, but any value other

 * Finally, there is a filter named 'editor_max_image_size', that will be called
 * on the calculated array for width and height, respectively. The second
 * parameter will be the value that was in the $size parameter. The returned
 * type for the hook is an array with the width as the first element and the
