[Laszlo-dev] What are we going to do about Sprite's wanting to register delegates?

[P T Withington]

It really turns out that LzDelegate and LzEvent want their context's  
to be LzMiniNode's (because they want to look at __LZdeleted,  
__LZdeferDelegates, and _events).  If all context's were LzMiniNodes  
(or LzEventable, as proposed yesterday), we could also implement  
automatic tracking of events and delegates so they won't leak when  
nodes are destroyed (eliminating the burden on every LZX class doing  
this for themselves).

I tried to enforce this, but run into trouble because Sprite's want to  
register themselves as delegates, but they are not mini nodes.

One thought:  I create a superclass LzSimpleDelegate and LzSimpleEvent  
that work with any object and don't participate in the node protocol.

Any better ideas?
