/**
* An Icon that scales its image to fill the component area, excluding any border or insets, optionally maintaining the image's
* aspect ratio by padding and centering the scaled image horizontally or vertically.
*
* The class is a drop-in replacement for ImageIcon, except that the no-argument constructor is not supported.
*
* As the size of the Icon is determined by the size of the component in which it is displayed, StretchIcon must only be used
* in conjunction with a component and layout that does not depend on the size of the component's Icon.
