   * @section page_iface_wp_viewport_desc Description
   *
   * An additional interface to a wl_surface object, which allows the
   * client to specify the cropping and scaling of the surface
   * contents.
   *
   * This interface works with two concepts: the source rectangle (src_x,
   * src_y, src_width, src_height), and the destination size (dst_width,
   * dst_height). The contents of the source rectangle are scaled to the
   * destination size, and content outside the source rectangle is ignored.
   * This state is double-buffered, and is applied on the next
   * wl_surface.commit.
   *
   * The two parts of crop and scale state are independent: the source
   * rectangle, and the destination size. Initially both are unset, that
   * is, no scaling is applied. The whole of the current wl_buffer is
   * used as the source, and the surface size is as defined in
   * wl_surface.attach.
   *
   * If the destination size is set, it causes the surface size to become
   * dst_width, dst_height. The source (rectangle) is scaled to exactly
   * this size. This overrides whatever the attached wl_buffer size is,
   * unless the wl_buffer is NULL. If the wl_buffer is NULL, the surface
   * has no content and therefore no size. Otherwise, the size is always
   * at least 1x1 in surface local coordinates.
   *
   * If the source rectangle is set, it defines what area of the wl_buffer is
   * taken as the source. If the source rectangle is set and the destination
   * size is not set, then src_width and src_height must be integers, and the
   * surface size becomes the source rectangle size. This results in cropping
   * without scaling. If src_width or src_height are not integers and
   * destination size is not set, the bad_size protocol error is raised when
   * the surface state is applied.
   *
   * The coordinate transformations from buffer pixel coordinates up to
   * the surface-local coordinates happen in the following order:
   * 1. buffer_transform (wl_surface.set_buffer_transform)
   * 2. buffer_scale (wl_surface.set_buffer_scale)
   * 3. crop and scale (wp_viewport.set*)
   * This means, that the source rectangle coordinates of crop and scale
   * are given in the coordinates after the buffer transform and scale,
   * i.e. in the coordinates that would be the surface-local coordinates
   * if the crop and scale was not applied.
   *
   * If src_x or src_y are negative, the bad_value protocol error is raised.
   * Otherwise, if the source rectangle is partially or completely outside of
   * the non-NULL wl_buffer, then the out_of_buffer protocol error is raised
   * when the surface state is applied. A NULL wl_buffer does not raise the
   * out_of_buffer error.
   *
   * The x, y arguments of wl_surface.attach are applied as normal to
   * the surface. They indicate how many pixels to remove from the
   * surface size from the left and the top. In other words, they are
   * still in the surface-local coordinate system, just like dst_width
   * and dst_height are.
   *
   * If the wl_surface associated with the wp_viewport is destroyed,
   * all wp_viewport requests except 'destroy' raise the protocol error
   * no_surface.
   *
   * If the wp_viewport object is destroyed, the crop and scale
   * state is removed from the wl_surface. The change will be applied
   * on the next wl_surface.commit.
   * @section page_iface_wp_viewport_api API
