Support for the pointer-gestures protocol
The pointer gestures protocol has been around for five years and is widely used in GTK apps, including Firefox, Gnome Web and evince, to allow touchpad pinch and zoom gestures. It would be great if we had support for it in Weston as well, as touchpad gestures are arguably one of the great features of Wayland.
