surface cropping and scaling
The global interface exposing surface cropping and scaling capabilities is used to instantiate an interface extension for a wl_surface object. This extended interface will then allow cropping and scaling the surface contents, effectively disconnecting the direct relationship between the buffer and the surface size.

unbind from the cropping and scaling interface
Informs the server that the client will not be using this protocol object anymore. This does not affect any other objects, wp_viewport objects included.

surface | the surface |
Instantiate an interface extension for the given wl_surface to crop and scale its content. If the given wl_surface already has a wp_viewport object associated, the viewport_exists protocol error is raised.
