Its never been a problem for me either. Views and Picks are used in 
very specific places. I would be happy if they did not
inherit from Q3Object at all.

I agree.

Yes I think this is possible, though I don't really see the need except 
to make Quesa easier to understand.  I doubt it could possibly cause 
anyone
a problem as code using them already will not call 
Q3Shared_GetReference and hence it doesn't matter which copy of the 
pointer they call Dispose on.
