By default, the pan action performs matrix translations on the child widget. Nobody wants that (or, nobody wants *just* that). It's cleaner not to mix mechanism and effect in ClutterGestureAction subclasses, so drop this base implementation, and change the signal accumulator so it's more similar to event signals (not that it's used any longer, anyway).
