public PopupWindowPlacerBuilder throwsAssertException() {
		add(new ThrowsAssertExceptionPlacer());
		return this;
	}
Set the next PopupWindowPlacer that throws an AssertException because no solution has
been found by the time this placer is tried.  This is intended to be used when the coder
has already guaranteed that there is a solution (i.e., the {@link #leastOverlapCorner()}
placer has been used and the pop-up area will fit within the outer bounds).
