Hi Team,

While going through Blink commits, I came across a helper, which reduces few multiplication etc.

Blink Commit: https://src.chromium.org/viewvc/blink?view=revision&revision=167603 (Helper function) and https://src.chromium.org/viewvc/blink?revision=168929&view=revision (Use in Canvas etc.)

___

If we add new rotateRadians function, we will be able to reduce unnecessary operations.

 Before : rad -> rad2deg -> deg2rad -> calc sinNcos
 After  : rad                       -> calc sinNcos

As a result, we can reduce two multiplication and two division.

___

It benefits by doing above.

So just wanted to raise, so I can do PR.

Thanks!
