f if the gesture was handled, and
t if the gesture should be passed on to the gadget's parent.
The default implementation looks at the
"gestures" word property of each superclass of the gadget's class.
NotesMethods should be defined on this word if you desire to handle an arbitrary set of gestures. To define handlers for a fixed set, it is easier to use
set-gestures. If you define a method on
handle-gesture, you should also override
handles-gesture?.
