2. Your canvas looks excessively complex to me. Are you sure we need
canvas item model/renderer separation? I think you need it if:
a) You want to store data that is specific for per item-view
pair;
Example: some caching of pixel coordinates, or something like that, I
don't know..
One of the things we need in a canvas is the ability to report the
objects drawn in it as objects, and report the bounding boxes and
stacking order of those objects. This is needed for accessibility
purposes; it might be easier to do this with a model/renderer
separation, I am not sure.
