Oh, huh.  You're right.  It does still have the language about aural
sheets.  Well, that's clearly wrong, as angles are now used in
Transitions, gradients, and several other properties.

As I said, the "normalized to 0-360deg" was discussed, and will be
removed.  It just hasn't happened yet.

Well, we've already got implementations of transformations.  Luckily,
they do the right thing with angles (they don't normalize).  We also
have an implementation of gradients which uses angles properly.  We
just need to get the draft updated appropriately.
