A base class for Resize, providing:
141
* Basic Lifecycle (initializer, renderUI, bindUI, syncUI, destructor)
142
* Applies drag handles to an element to make it resizable
143
* Here is the list of valid resize handles:
144
`[ 't', 'tr', 'r', 'br', 'b', 'bl', 'l', 'tl' ]`. You can
145
read this list as top, top-right, right, bottom-right, bottom,
146
bottom-left, left, top-left.
147
* The drag handles are inserted into the element and positioned
148
absolute. Some elements, such as a textarea or image, don't support
149
children. To overcome that, set wrap:true in your config and the
150
element willbe wrapped for you automatically.
