Add property to not modify DOM during the resize

[TiagoJacobs]

This component is awesome and simple to use.

We have an "edge case" that's the ability to use the component without applying the DOM changes on resize event ( mouse move ).

This means that we would like an option to manually apply the resize using the onResize callback, this way we would apply the resize manually ( other components are calculated together ).

A property named skipDomChangeOnResize would be awesome. If it's defined and with value === true, the component would not apply any changes in DOM during the mousemove ( only call the onResize callback ).
