distributors translate a moving cursor into

CSS/DOM changes by calling the sizer

they have two methods:
|

`resize` receives then new item size

`resizeFromContainerOffset` receives resize handle location

within the container bounding box. For internal use.

|
This method usually ends up calling `resize` once the start offset is subtracted.
