We know support EV_REL events comming from evdev devices. This addition is pretty straigthforward, it adds a x,y per GSource listening to a evdev device, updates from EL_REL (relative) events and craft new ClutterMotionEvents. As for buttons, BTN_LEFT..BTN_TASK are translated to ClutterButtonEvents with 1..8 as button number.
