-    <description summary="crop and scale interface to a wl_surface">
-      An additional interface to a wl_surface object, which allows the
-      client to specify the cropping and scaling of the surface
-      contents.
-
-      This interface allows to define the source rectangle (src_x,
-      src_y, src_width, src_height) from where to take the wl_buffer
-      contents, and scale that to destination size (dst_width,
-      dst_height). 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 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, the surface size becomes the source
-      rectangle size rounded up to the nearest integer. If the source size
-      is already exactly integers, this results in cropping without scaling.
-
-      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 (wl_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 the source rectangle is partially or completely outside of the
-      wl_buffer, then the surface contents are undefined (not void), and
-      the surface size is still dst_width, dst_height.
-
-      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 wl_viewport is destroyed,
-      the wl_viewport object becomes inert.
-
-      If the wl_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.
