+/**
+ * Controller for assigning layers to windows on the display.
+ *
+ * This class encapsulates general algorithm for assigning layers and special rules that we need to
+ * apply on top. The general algorithm goes through windows from bottom to the top and the higher
+ * the window is, the higher layer is assigned. The final layer is equal to base layer +
+ * adjustment from the order. This means that the window list is assumed to be ordered roughly by
+ * the base layer (there are exceptions, e.g. due to keyguard and wallpaper and they need to be
+ * handled with care, because they break the algorithm).
+ *
+ * On top of the general algorithm we add special rules, that govern such amazing things as:
+ * <li>IME (which has higher base layer, but will be positioned above application windows)</li>
+ * <li>docked/pinned windows (that need to be lifted above other application windows, including
+ * animations)
+ * <li>dock divider (which needs to live above applications, but below IME)</li>
+ * <li>replaced windows, which need to live above their normal level, because they anticipate
+ * an animation</li>.
