Guile's bindings make all functions returning and taking GdkEvent deal
in GdkEvent*, i.e. not GdkEventButton* or whatever.

To access fields of the event structure there are accessors like
gdk-event-button-press:x, which is implemented as:

1) call a C routine to convert the event struct to a vector
2) check the type of the event
3) access well-known elements of that vector (e.g. third element is x)

You can't create gdkevents in guile-gnome, afaik.

Dunno how this all melds with the introspection stuff.
