What's the default style?
What's the default CSS style for a model element? Should it have a border around it? what about background color? etc.
My sense is that 3D content is so different in scale that there's not useful information from the boundingBoxExtents of a given asset - there will be an appropriate aspect ratio, given the bounding box's X and Y dimensions - but I don't think it's a strong enough signal to use to determine the page content dimensions.

To be discussed with CSS working group
CSSWG:
- Can it be opaque?
- How to define an only opaque color?
- No background gradient or image
- What do we do with unsupported CSS properties e.g. perspective transforms & skew
Let's investigate 300x300 for aspect ratio reasons. (No strong preference but worth investigating)
