Function wrap

wrap(
    pt: Geometry.Point,
    ptMax?: Geometry.Point,
    ptMin?: Geometry.Point,
): Geometry.Point
Wraps a point to be within ptMin and ptMax. Note that max values are exclusive, meaning the return value will always be one less.

Eg, if a view port is 100x100 pixels, wrapping the point 150,100 yields 50,99.
```
// Wraps 150,100 to on 0,0 -100,100 range
wrap({x:150,y:100}, {x:100,y:100});
```
Wrap normalised point:
```
wrap({x:1.2, y:1.5}); // Yields: {x:0.2, y:0.5}
```
Parameters
- pt: Geometry.Point
  Point to wrap
- OptionalptMax: Geometry.Point
  Maximum value, or { x:1, y:1 } by default
- OptionalptMin: Geometry.Point
  Minimum value, or { x:0, y:0 } by default
Returns Geometry.Point
Wrapped point
