This protocol specifies a set of interfaces used to control the behavior of stylus tools. Warning! The protocol described in this file is experimental and backward incompatible changes may be made. Backward compatible changes may be added together with the corresponding interface version bump. Backward incompatible changes are done by bumping the version number in the protocol and interface names and resetting the interface version. Once the protocol is to be declared stable, the 'z' prefix and the version number in the protocol and interface names are removed and the interface version number is reset. The global interface is used to instantiate an interface extension for a wl_surface object. This extended interface will then allow the client to control the stylus-related behavior for input device event processing related to wl_surface. Informs the server that the client will not be using this protocol object anymore. This does not affect any other objects, stylus_tool objects included. Instantiate an interface extension for the given wl_surface to provide access to the stylus tools features. If the given wl_surface already has an stylus_tool object associated, the stylus_tool_exists protocol protocol error is raised. An additional interface to a wl_surface object, which allows the client to control the behavior of stylus tools. If the wl_surface associated with the stylus_tool object is destroyed, the stylus_tool object becomes inert. If the stylus_tool object is destroyed, the stylus_tool state is removed from the wl_surface. The change will be applied on the next wl_surface.commit. The associated wl_surface's stylus_tool state is removed. The change is applied on the next wl_surface.commit. Enables the "stylus-only" mode for input device event processing related to wl_surface.
