DoAngular()

//Functions to converty angular behaviour to directional, based on the angle.
//Call when setting bool Angular for an object, as Angular = DoAngular(ptr)
//This ensures that the lack of decimal precision in conversion to Allegro radians
//does not prevent setting certain angles; causing 'drift'.
