Details

The MapNotify event is required in the xlib mainloop to notify the widget code that a window has been mapped. Without this information you can't safely use XSetInputFocus() on a window. The mIsMapped member variable in the nsWidget object holds this state information. Also, the tight loop in HandleConfigureNotifyEvent that will get the last ConfigureEvent will drop MapNotify events on the floor without passing Go or collecting $200. This is because it will use a XCheckWindowEvent() with a StructureNotifyMask and not handle any MapNotify events. Badness. Must fix.

Figured out how to work around this. Also, not needing to track MapNotify anymore. Closing this chapter.
