An overpass method is a method created to bridge to a default method in an interface today.
An overpass method does NOT require a vtable entry to be created because we only create
them with names matching current miranda methods, so the overpass method will re-use
the miranda method's vtable entry. 

I should have been clearer - an overpass method does not require a NEW vtable entry,
it does use a vtable entry.
