Libinput is an optional dependency for getting low level input events. As opening the input devices requires root privs this is rather pointless in the current state. But there is a small added test app which can be executed with root privs to demonstrate the functionality. To properly get input events we need a wrapper like it's used in weston. So far the following is setup: * opening devices found by udev * forwarding keyboard events to InputRedirection * forwarding pointer button events to InputRedirection * forwarding pointer axis events to InputRedirection * signals emitted for pointer motion events Pointer motion events need some further work as they are provided as delta events. We need to track that and map them properly. Also missing are touch events due to me not having a touch screen. It should be fairly simple to setup the touch events, though. Also hotplugging of devices is not yet implemented.
