- * wl_viewport - crop and scale interface to a wl_surface
- * @destroy: remove scaling and cropping from the surface
- * @set: set the crop and scale state
- * @set_source: set the source rectangle for cropping
- * @set_destination: set the surface size for scaling
- *
- * 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.
