/**
 * Plugin for testing ad layout
 *
 * This plugin uses the UAPPlugin framework to output ad content. However,
 * its ad content is just images with one red pixel stretched to the
 * right size. It's mostly useful for debugging theme layout.
 *
 * To use this plugin, set the parameter for the ad size you want to use
 * to true (or anything non-null). For example, to make a leaderboard:
 *
 *     addPlugin('BlankAd', array('leaderboard' => true));
