[mutter/wip/carlosg/capabilities-and-dimensions: 8/11] clutter: Add clutter_input_device_get_dimensions()

[Carlos Garnacho <carlosg src gnome org>]

    clutter: Add clutter_input_device_get_dimensions()
    
    This will be used to know the size of touchscreens and tablets
    by poking the backends about it. This is intended to replace code
    using udev nowadays.
