        // This function is magic

        // The issue here is that Pano makes bad assumptions about rotation and

        // orientation. The first is it assumes only two rotations are possible,

        // 0 and 90. Thus, if display rotation is >= 180, we invert the output.

        // The second is that it assumes landscape is a 90 rotation from portrait,

        // however on landscape devices this is not true. Thus, if we are in portrait

        // on a landscape device, we need to invert the output
