A {@link SimplePanel} that wraps its contents in stylized boxes, which can beused to add rounded corners to a {@link Widget}.
Wrapping a {@link Widget} in a "9-box" allows users to specify images in eachof the corners and along the four borders. This method allows the content within the {@link DecoratorPanel} to resize without disrupting the look ofthe border. In addition, rounded corners can generally be combined into a single image file, which reduces the number of downloaded files at startup. This class also simplifies the process of using AlphaImageLoaders to support 8-bit transparencies (anti-aliasing and shadows) in ie6, which does not support them normally.
If you set the width or height of the {@link DecoratorPanel}, you need to set the height and width of the middleCenter cell to 100% so that the middleCenter cell takes up all of the available space. If you do not set the width and height of the {@link DecoratorPanel}, it will wrap its contents tightly.
