Figure 8.1: CLIM event classes. All classes that appear at a given indentation are subclasses of
the class that appears above and at a lesser indentation.

=> :timestamp [Init Arg]
All subclasses of event must take a :timestamp initarg, which is used to specify the timestamp
for the event.

=> event-timestamp event [Generic Function]
Returns an integer that is a monotonically increasing timestamp for the the event event. The
timestamp must have at least as many bits of precision as a fixnum.

=> event-type event [Generic Function]
For the event event, returns a keyword with the same name as the class name, except stripped
of the "-event" ending. For example, the keyword :key-press is returned by event-type for
an event whose class is key-press-event.

All event classes must implement methods for event-type and event-timestamp.

=> device-event [Class]
=> :sheet [Init Arg]
=> :modifier-state [Init Arg]
The class that corresponds to any sort of device event. This is a subclass of event.
