/**
 * Demonstrates how to use IconPainter.
 * 
 * IconPainter can efficiently render large numbers of icons in fixed 
 * locations in data space by leveraging a TextureAtlas to store the icon images.
 *
 * Picking support is also provided, allowing the IconPainter to report on
 * the identity of icons under the current mouse location.
 *
 * Tested with 100,000 individual icons on Nvidia GTX 480. Less with a large number
 * of icon groups.
