-    This is the alternative and convenient solution of wl_viewport to present
-    a subsurface on screen.
-
-    The below five functions can be replaced with this interface. The below
-    functions will be ignored after applying this interface to a subsurface.
-     - wl_surface.set_buffer_transform
-     - wl_surface.set_buffer_scale
-     - wl_subsurface.set_position
-     - wl_viewport.set_source
-     - wl_viewport.set_destination
-
-    wl_viewport.set_source is very complicated especially when the buffer of
-    wl_surface is transformed by wl_surface.set_buffer_transform. And when the
-    parent is resized, if we want to change the geometry of a subsurface also,
-    wl_subsurface.set_position and wl_viewport.set_destination should be called
-    everytime the parent is resized in client side. This makes difficult to
-    synchronize a parent surface and a subsurface on screen.
-
-    tizen_viewport allows clients to set the relative geometry to a subsurface
-    in a parent surface. Whenever a parent surface is resized, the geometry of
-    a subsurface will be calculated, moved and resized automatically by a
-    compositor.
-
-    The tizen_viewport is specified in the coordinates of a subsurface's parent.
-
-    The below 3 functions don't consider the transform of a parent's surface.
-     - tizen_viewport.set_source
-     - tizen_viewport.set_destination
-     - tizen_viewport.set_destination_ratio
-
-    However, tizen_destination_mode.follow_parent_transform is called,
-    tizen_viewport will consider the transform of a parent surface when applying
-    the destination mode to a subsurface.
-
-    The destination will be cropped by a parent surface.
-
-    The change will be applied when wl_surface.commit is called.

-    The accepted values for the transform parameter are the values for wl_output.transform
-    according to the output transform.
-
-    The tizen_viewport.set_transform is applied only to itself. Basically it
-    doesn't effect the transform of its subsurfaces. That is, if 90 transform is
-    setted and its subsurface has 0 transform, its subsurface won't be
-    rotated.
-
-    If need to rotate the subsurface depended on a parent surface,
-    tizen_viewport.follow_parent_transform will make it possible.
