A ScreenWrap manipulated the XY of a point, if it travels outside the wrap space.

let topLeft = [50, 50]
    , bottomRight = [800, 800]

s = new ScreenWrap(topLeft, bottomRight)

Check and alter point positions as they move in the draw routine:

s.perform(point)

This is setup be default on the stage, saving the setup part and screen resize tracking:

stage.screenWrap.perform(point)
