John's fix for the minimize/close/maximize controls no longer working.

WIN32 expected us to pass the message on up the chain (or do something
else with it), rather than just throwing away the event, for a certain
class of events.  (See the diffs for more details.)

The code is also slightly reformatted from what was previously in the
repository.
