It's done this way because a widget can have multiple drop
zones internal to it, and the drop zones might not be
the entire widget - whether the drop is inside the widget
is determined by the boolean return value of "drag_motion" -
so a "drag_enter" separate from a "drag_motion" doesn't really
make sense.
(If you specify GTK_DRAG_DEFAULT_MOTION then the drop zone corresponds
to the widget, then the drop zone is the entire widget, and GTK+
handles the return value for you, but it doesn't have to be that
simple)

Owen
