Well, this raises the point: what ideal is the LDraw format aiming for? I
don't think it's really going anywhere; any real change to the format would
break compatability with the legacy LDRAW.EXE.
I'm proposing a class library for the existing codebase and modelbase that
is already out there.

It's true that a renderer is a View object, but why can't you have Models,
Views, and Controllers in the same class library?
The Controller aspect, is, of course, the API -- in the sense that you use
it to modify elements in the Model.

Here's my Javadoc of *working* code as of today:

I don't intend this to be the foundation of anything we develop; it's merely
what I wrote last week and propose as a general class structure.
