LogindIntegration starts monitoring the Active property on the session
and emits a signal when the state changes. The LibInput::Connection
connects to this signal during the setup and uses it to suspend/resume
the libinput context.
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.
