update_coordinates

def update_coordinates (   self,   parent_center = None,   reference_coordinate = None,   matrix_to_global = None   ) do a complete transform of our angular coordinates and positions to a new frame. Our rotation is adjusted from its current value by matrix_to_global. Our center is moved to parent_center+rotated value of (self.center-reference_coordinate). This is used when we are embedded in a composite optic, and the whole composite optic is moved or rotated. Reimplemented in composite_optic.
