The protocol described in this file is experimental and backward 32 incompatible changes may be made. Backward compatible changes may be added 33 together with the corresponding interface version bump. Backward 34 incompatible changes are done by bumping the version number in the protocol 35 and interface names and resetting the interface version. Once the protocol 36 is to be declared stable, the 'z' prefix and the version number in the 37 protocol and interface names are removed and the interface version number is 38 reset. 39 </description> 40 41 <interface name="zcr_stylus_tools_v1" version="1"> 42 <description summary="stylus_tools"> 43 The global interface is used to instantiate an interface extension for a 44 wl_surface object.
