We could start a branch. I've removed most of the model/view split in my
code here.

The problem is agreeing on what should be in any new API...

I'm tempted to allow all items to have children, since sometimes this
can be handy, to quickly add things like drag handles. (QGraphicsView
allows this, I think.) I'm not sure yet though.

I still don't really like this. If you want to add those properties to your
own items you're welcome, but I'm not sure about forcing everyone to do that.

Plus we already have the transformation matrix which provides a common
interface to position items.
