Does anyone have any code for window zooming?  I've been trying to
get a window to zoom, but I must not be doing something right.

I created a window of the correct type, and I receive inZoomOut
events when I click in it.  Am I supposed to diddle with the
WStateData in the DataHandle part of the WindowRecord?  I tried
to initialize the values, but had trouble dereferencing and
typecasting DataHandle.  I finally got something to compile by
dereferencing DataHandle to a pointer, 'casting that, and storing
some rectangles there.

Playing around in the Debugger shows that I _always_ receive
inZoomOut events, never inZoomIn.  When I get the event, I call
TrackBox and ZoomWindow.  The window just blinks.

Sorry for the lack of details, but the code's at home.  Any ideas?
