What every widget skin shares: the atlas its regions come from, and how
much of each region's edge is kept unscaled when it is stretched.
A region drawn bigger than its art is drawn as a nine-slice: the corners
keep their size and the edges and middle stretch, so a 190 pixel wide
button image makes a button of any width.
