gtk:gesture-point (gesture sequence)

gesture -- a gtk:gesture object
sequence -- a gdk:event-sequence instance, or nil for pointer events
x -- a double float for the x axis of the event sequence coordinates
y -- a double float for the y axis of the event sequence coordinates

If sequence is currently being interpreted by gesture, this function returns x and y with the last coordinates stored for that event sequence. The coordinates are always relative to the widget allocation.
