+/* The algorithm for docking and redocking implemented here
+ * has a couple of nice properties:
+ *
+ * 1) During a single drag, docking always occurs at the
+ * the same cursor position. This means that the users
+ * motions are reversible, and that you won't
+ * undock/dock oscillations.
+ *
+ * 2) Docking generally occurs at user-visible features.
+ * The user, once they figure out to redock, will
+ * have useful information about doing it again in
+ * the future.
+ *
+ * Please try to preserve these properties if you
+ * change the algorithm. (And the current algorithm
+ * is far from ideal). Briefly, the current algorithm
+ * for deciding whether the handlebox is docked or not:
+ *
+ * 1) The decision is done by comparing two rectangles - the
+ * allocation if the widget at the start of the drag,
+ * and the boundary of hb->bin_window at the start of
+ * of the drag offset by the distance that the cursor
+ * has moved.
+ *
+ * 2) These rectangles must have one edge, the "snap_edge"
+ * of the handlebox, aligned within TOLERANCE.
+ *
+ * 3) On the other dimension, the extents of one rectangle
+ * must be contained in the extents of the other,
+ * extended by tolerance. That is, either we can have:
+ *
+ * <-TOLERANCE-|--------bin_window--------------|-TOLERANCE->
+ * <--------float_window-------------------->
+ *
+ * or we can have:
+ *
+ * <-TOLERANCE-|------float_window--------------|-TOLERANCE->
+ * <--------bin_window-------------------->
