     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.

       It provides requests to treat surfaces like windows, allowing to set
       properties like app id and geometry.
 
       The client must call wl_surface.commit on the corresponding wl_surface
       for the remote_surface state to take effect.
