Bundel of information passed to this shape and all of its desendants.

Index used to disambiguate between objects that have the same

z-order instead. Because that is not a good substitute, better
pass an ever increasing counter.
@attention
Always call the <member>init</member> method after creating a
new accessible shape. This is one way to overcome the potential
problem of registering the new object with e.g. event
broadcasters. That would delete the new object if a broadcaster
would not keep a strong reference to the new object.
