Adding rotation to arbitrary angle would require implementing of sines
and cosines. And this risks to be terribly slow. Additionally few gfx
drivers support such rotation. I really see no reason for such
headache for us either. To make long story short rotation to arbitrary
angle is a NO WAY as far as I'm concerned
