A component that resizes its parent component when dragged.

This component forms a bar along one edge of a component, allowing it to

be dragged by that edges to resize it.
|

To use it, just add it to your component, positioning it along the appropriate
|
|
edge. Make sure you reposition the resizer component each time the parent's size
|
|
changes, to keep it in the correct position.

resize this component to keep it in place, as this won't happen automatically.
