Here’s my related stack overflow answer, which uses the technique to make a shadow around a UITableView section of arbitrary size and shape.

Android has a “file format” (really just an image with some magic lines at the edges) called 9-patch that allows you to set this up automagically. It’s neat!

Interesting… here’s a link. I guess that’s what they use for their resizeable buttons. Thanks Greg :)
