+//  WindowDataMap
+// 
+//  In both mozilla and embedding apps, we need to have a place to put
+//  per-top-level-window logic and data, to handle such things as IME
+//  commit when the window gains/loses focus. We can't use a window 
+//  delegate, because an embeddor probably already has one. Nor can we
+//  subclass NSWindow, again because we can't impose that burden on the
+//  embeddor.
+// 
+//  So we have a global map of NSWindow -> TopLevelWindowData, and set
+//  up TopLevelWindowData as a notification observer etc.
