The function expects input, and returns values in ClutterUnits, not
pixels. The event coords are in pixels, so you need to convert them
first with CLUTTER_UNITS_FROM_DEVICE, and then also convert the result
to pixels with CLUTTER_UNITS_TO_DEVICE for the human-readable output.

Yes, if the actor is rotated or at non-0 depth, that will certainly
effect the result, which is in the coordinate space of the actor (self).
