DND source sites don't need to be registered.

There is no reason to use gtk_drag_source_set() if you don't
want to use gtk_drag_source_set().
If you don't want to use gtk_drag_source_set(), simply call
gtk_drag_begin() from your motion handler.
(BTW - using a different threshhold would be broken. At some
point the GTK+ threshhold will be user configurable - and if
you don't use the GTK+ value, then your drag source won't
follow the user's settings.)
