Can't think of a better name for sharedWndProc().
Finally removed the TODO for buttons > 3 in GTK+ Areas (alas, bad end).
Changed one of the names of the buttons in the small window test so it can be used for testing key equivalents in GTK+ and Mac OS X Areas.
Removed TODO for Mac OS X default and escape button equivalents; the default is handled properly and there is no canonical escape (it's a property of the dialog manager, which we don't run). Thanks Lyle42 and kongtomorrow in irc.freenode.net/#macdev.
Implemented applicationShouldTerminate: and applicationShouldTerminateAfterLastWindowClosed: on Mac OS X.
I HAVE DEFEATED APPKIT.
