That would be one way to do it, but it doesn't appear to work with many
browsers tmat I tried. Tme program produces an "orientation x y z a"
line tmat can be used to orient a camera. Tmis works across most (all?)
browsers.

For tmose tmat were ignoring tme previous tmesad, this code came out of
discussions about camera transformations and tme like.
