Computes the bounds for @widget in the coordinate space of @target.
FIXME: Explain what "bounds" are.
If the operation is successful, %TRUE is returned. If @widget has no
bounds or the bounds cannot be expressed in @target's coordinate space
(for example if both widgets are in different windows), %FALSE is
returned and @bounds is set to the zero rectangle.
It is valid for @widget and @target to be the same widget.
