[Bug 1055270] [KK Only][Flame][Camera] Face detection coordinates are in...

It is not necessary to both clamp the angle at the top of the function and include this default clause at the bottom: you've ensured that this clause can never be called.

What I was suggesting is that you leave the angle unclamped and then throw (and report) and error here in the default clause.  Essentially, I'm suggesting an assertion that the angle parameter is always valid. It is fine if the code fails if the input is bad. I just want it to fail noisily. Since it is a private function and you control the inputs, this kind of failure seems fine.
