[Squeakland] a question about siblings

Hi Randy --

The idea of siblings is to make parametrically similar objects. So it's an 
interesting question just which parameter values should be transmitted or 
remain distinct. If the "graphic" is repainted on a sibling, we certainly 
don't want the change to be automatically propagated to the rest (any more 
than we want the position or heading be automatically transmitted). OTOH, 
we might want to selectively transmit some of the values from one object to 
all. E.g. we might want to say "let all my siblings have my graphic".

Right now we are pretty much restricting this to control state rather than 
property values ....
