/**
 * Package private method which returns either BorderLayout.NORTH,
 * BorderLayout.SOUTH, BorderLayout.EAST, or BorderLayout.WEST depending
 * on the location of the toolbar in its parent. The toolbar might be
 * in PAGE_START, PAGE_END, CENTER, or some other position, but will be
 * resolved to either NORTH,SOUTH,EAST, or WEST based on where the toolbar
 * actually IS, with CENTER being NORTH.
 *
 * This code is used to determine where the border line should be drawn
 * by the custom toolbar states, and also used by NimbusIcon to determine
 * whether the handle icon needs to be shifted to look correct.
 *
 * Toollbars are unfortunately odd in the way these things are handled,
 * and so this code exists to unify the logic related to toolbars so it can
 * be shared among the static files such as NimbusIcon and generated files
 * such as the ToolBar state classes.
