    My concern is that the various working groups (Web3D, WHATWG, et 
cetera) will play pass the buck on this issue. Can we create a generic 
spec for displaying 3D information in a 2D window? We could allow the 
X3D spec or other specs to override if they needed to.

    Oops!

| x3d|X3D {
|   width: 100px;
|   height: 100px;

    The <div> element is not the right element for what? I'm not even

    I've already come to that conclusion elsewhere in this thread.
