The centerRect allows you to stretch a portion of an image without 
affecting the areas outside of the rectangle. Imagine you have an image 
with rounded corners and you want to use it as a button icon. You can 
specify an area in the center of the image that can stretch as wide as you 
need the button to be but the corners won't be affected and will keep their 
original radius.

Or imagine a vertical image like a paper bookmark with a design on top and 
a cutout shape on the bottom. You could stretch the center area to make it 
taller without distorting the top design or the cutout at the bottom.
