Summary: This change implements the zwp_relative_pointer_v1 protocol which allows to send relative motion events. The (unstable) protocol consists of a RelativePointerManager which creates RelativePointers for a given Pointer. This interface currently only has one event to report the relative motion. It carries the delta, the non-accelerated-delta and a timestamp in microsends granularity. On the server side the implementation is mostly internal. Once a RelativePointerManagerInterface is created one can send relative motion events through the SeatInterface. The SeatInterface takes care of sending it to the responding RelativePointerInterface. The protocol does not restrict the sending of "normal" and relative motion events. Thus it can be combined in any way one wants. This allows to have a rather simple implementation. A user of the SeatInterface can just start to feed the relative motion events (if the information is available) to the SeatInterface together with the pointer events. On client side a new RelativePointerManager and RelativePointer class are added. The RelativePointerManager creates the RelativePointer for a given Pointer. The event sent to RelativePointer is transformed in a normal signal. Reviewers: #plasma Subscribers: plasma-devel Tags: #plasma_on_wayland Differential Revision: https://phabricator.kde.org/D2978
