Decided to drop the whole handled thing with Area events and just continue the event chain if needed. Same for MousEvent; will have to document that. This is just the test program for now.
Documented the changed event handling of Area.
Implemented the new Area event handling on Windows.
Applied the new Area event behavior to the GTK+ backend. Yay, loads of TODOs resolved in one fell swoop!
Removed some more commented-out code from ages ago from area_unix.go.
Applied the Area events change to the Mac OS X backend, restructuring a few function signatures in the process.
