+This class represents an input device that was registered with Wayland. |
+The purpose of this class is to parse and wrap events into generic |
+WaylandEvent types and dispatch the event to the appropriate WaylandWindow. |
+ |
+How Wayland events work: |
+------------------------ |
+ |
+When the On*Focus events are triggered, the input device receives a reference |
+to the surface that just received/lost focus. Each surface is associated with |
+a unique WaylandWindow. When processing the focus events we keep track of the |
+currently focused window such that when we receive different events (mouse |
+button press or key press) we only send the event to the window in focus. |
