/*
* Setting a context is sort of like the GTK concept of "realization"
* - it does not necessarily map to the item being in a container, and
* in fact the root item has a context but would not have a parent
* container, for example. Also an item can be in a container item and not
* have a context if the container item does not have a context, for
* example if the whole tree of items is not in a HippoCanvas widget.
*
* If for example we were printing a tree of canvas items, we
* might have to temporarily set the context to a special print
* context (though this has problems, such as temporarily unrealizing
* any widget items; so print support may require larger changes than
* just creating a print context).
