+====== X-ray Windows ======
+The X-ray windows display the X-rays of each view, as well as POIs, POI trails, reference frames, and landmarks. The //Points of Interest// widget lets you choose which POIs and POI trails to display on the X-rays. The //View// menu has commands for toggling the display of the reference frame and landmarks of the current object, and the POIs of all of the other objects.
