    Return the closest point to the given point, for example the nearest point to the mouse. Return the most near point at any distance: > distances.closest(mouse.position) point Return the most near point, also within 100px radius distance: > distances.closest(mouse.position, 100) Of which is the same as: // within 100px of the mouse position > distances.within(100, mouse.position)

      Check if a point _intersects_ another point, returning the interecting top point. > intersect(mouse) point // a point under the mouse. To _pad_ the overlap distance, provide an addition padding value: > intersect(mouse, 10) // add 10px around the perimeter point Useful if the intersection point has a radius: > intersect(mouse, mouse.radius) // add 10px around the perimeter This is the same as calling `closest()`, with the second arg as a function for radius testing.

      Each distance is tested against the curent _low_. If the distance `v` is less than `low`, store `p`. In the first iteration, `setterFunc`, does not do a test, and replaces _itself_, with a testing function. This ensures we don't need to check for the first `undefined` .
