+/** An object that watches for any movement of a component or any of its parent components.
+
+    This makes it easy to check when a component is moved relative to its top-level
+    peer window. The normal Component::moved() method is only called when a component
+    moves relative to its immediate parent, and sometimes you want to know if any of
+    components higher up the tree have moved (which of course will affect the overall
+    position of all their sub-components).
+
+    It also includes a callback that lets you know when the top-level peer is changed.
+
+    This class is used by specialised components like WebBrowserComponent
+    because they need to keep their custom windows in the right place and respond to
+    changes in the peer.
