Functions

func Edge

func Edge(ci, max int, wrap bool) (int, bool)

Edge returns coordinate value based on either wrapping or clipping at the edge and if not wrapping, if it should be clipped (ignored)

func WrapMinDist

func WrapMinDist(ci, max, ctr float32) float32

WrapMinDist returns the wrapped coordinate value that is closest to ctr i.e., if going out beyond max is closer, then returns that coordinate else if going below 0 is closer than not, then returns that coord
