13 //  In both mozilla and embedding apps, we need to have a place to put
14 //  per-top-level-window logic and data, to handle such things as IME
15 //  commit when the window gains/loses focus. We can't use a window
16 //  delegate, because an embeddor probably already has one. Nor can we
17 //  subclass NSWindow, again because we can't impose that burden on the
18 //  embeddor.
19 //
20 //  So we have a global map of NSWindow -> TopLevelWindowData, and set
21 //  up TopLevelWindowData as a notification observer etc.
