A checkbox is a view and a controller for a model. The checkbox itself has
no state, it's model does. It could be implemented as one graphic, but it
isen't and I can't think of any reason why it should be.

Both, the fat- and the small-graphic solution, is a way to go. That's why I
am asking. I am personally with the tiny graphics...

In the case of the HTML-renderer reading some file (from the net or
whereever), processing that to obtain a DOM and then figuring out how
that DOM should be rendered is a problem of the model, which lives in
the client. The actual rendering and notifying about changes to interactive
elements (view and controller) belong into the server as Graphics and
Controllers. At least that's how I think about this problem.

So to me a HTML-Renderer would be some client library, that creates lots of
small graphics in the server underneath some root graphic the client
developer chooses.

Your suggestion seemed to be to have a HTML-Kit that is a factory
for HTML-Renderer graphics which get added into the scenegraph and then acts
as a factory there by producing it's children. Why would we want such a
"factory" as a node in the scenegraph when it does not contribute to the
rendering itself?
