internal struct data in libgnomeui and libgnomecanvas

[Marc Mulcahy <marc mulcahy sun com>]

I have begun an accessibility review of libgnomeui, and have just completed 
one for libgnomecanvas.  The widgets in these libraries contain what appear 
to be public data members in their data structures, and hide private data 
in "priv" data structures.  External libraries which would potentially 
implement accessibility on behalf of these libraries, as GAIL does for GTK+ 
currently, would need access to many of these "public" variables.  Is this 
acceptable?  If not, then a substantial number of accesser functions would 
need to be added to these libraries to support accessibility.

Comments?
