/*
 * Toggles the layer between a solid and gradient fill.
 * Written by Richard Z. - richkzad@gmail.com
 *
 * Thanks to Yasuyuki Higuchi and Scott Weichert for tips on how to reproduce
 * the functionality by creating an action in Photoshop CS3 and then running
 * it in Photoshop CS4
 * http://www.adobeforums.com/webx?128@@.59b6e5bb
 *
 * Thanks to xbytor for writing a script that would convert an action into
 * JavaScript to help understand what was really going on.
