Comment 7 for bug 1447499

I like the idea of using an X rather than a swooping arrow to indicate the rotation lock -- now that I look at them side-by-side, it seems clear to me the current icon describes what the phone /can't/ do because of the lock :-)

However I don't like the idea of adding an orientation-unlock.svg for two reasons: (1) when scaled down to the size of the panel, the lock and unlock icons look too siimilar, and (2) we are very short on real estate in the panel, so I'd prefer for no-icon-present to denote rotate unlocked.
