If there are touch sequences being currently handled by @gesture,
returns %TRUE and fills in @rect with the bounding box containing
all active touches.
Otherwise, %FALSE will be returned.
Note: This function will yield unexpected results on touchpad
gestures. Since there is no correlation between physical and
pixel distances, these will look as if constrained in an
infinitely small area, @rect width and height will thus be 0
regardless of the number of touchpoints.
