An element used for window resizing. If you place a custom resizing button inside the resizer, the user will be able to resize the window by dragging it. The resizer will send a command event after the resize is complete.

Note: Starting in Gecko 2.0, you can also specify a target element using the element attribute, to use the resizer to resize the specified element instead of the window.
