Erm, they are tagged and in some cases I have needed "aliased" to get
hold of the actual address of the item, i.e. when connecting an event
handler to a frame, you have to give it the address of the event
handler, the lib currently uses this address internally as well.

The lib is already a thick binding:

1) A mirror of the class hierarchy from C++ into Ada tagged types.
2) The primitive operations call imported C functions which in turn
call the necessary C++ methods.
3) Conversions between Ada and C types is done inside the lib and you
never deal with a C.int/long or chars_ptr.
