Rounded rectangle with gradient background on the iPhone, NSTokenFieldCell style.

Unlike my previous implementation, this one is drawn inside a single view using Core Graphics. It can thus be used for optimized, fast-scrolling cells per Apple's TableViewSuite sample.

The gradient shades are changed from that implementation, too, and the border itself is gradiented (by drawing a smaller rectangle inside a larger one that becomes the border).

You need to include the uicolor-utilities category by Ars Technica.
