/*
 * "ADD LANDMARK" BUTTON UPDATING LOGIC
 * 
 * If the current parcel has been landmarked, we should draw
 * a special image on the button.
 * 
 * To avoid determining the appropriate image on every draw() we do that
 * only in the following cases:
 * 1) Navbar is shown for the first time after login.
 * 2) Agent moves to another parcel.
 * 3) A landmark is created or removed.
 * 
 * The first case is handled by the handleLoginComplete() method.
 * 
 * The second case is handled by setting the "agent parcel changed" callback
 * on LLViewerParcelMgr.
 * 
 * The third case is the most complex one. We have two inventory observers for that:
 * one is designated to handle adding landmarks, the other handles removal.
 * Let's see how the former works.
 * 
 * When we get notified about landmark addition, the landmark position is unknown yet. What we can
 * do at that point is initiate loading the landmark data by LLLandmarkList and set the
 * "loading finished" callback on it. Finally, when the callback is triggered,
 * we can determine whether the landmark refers to a point within the current parcel
 * and choose the appropriate image for the "Add landmark" button.
 */

/**
 * Initiates loading the landmarks that have been just added.
 *
 * Once the loading is complete we'll be notified
 * with the callback we set for LLLandmarkList.
