[PATCH weston v3 3/5] clients: Request the wl_pointer_gesture_swipe/pinch interfaces
Carlos Garnacho
carlosg at gnome.org
Fri Jul 31 06:59:53 PDT 2015
This is accompanied by separate handlers for the different stages
of swipe/pinch gestures, so those can be set in demos.
v3: added null checks around pointer gesture interface destruction,
nullify afterwards.
v2: depend on standalone protocol xml.
