 * It also uses a sine wave to control the opacity, rather than linearly
 * bouncing between its maximum and minimum opacity levels.
 *
 * Default settings create a slower pulse over a narrower range of opacity
 * levels.
 *
 * You can customize the speed of the pulse, and minimum and maximum levels of
 * opacity, by editing this plugin. Don't be afraid! It's easy! The values to
 * change are clearly labeled, and near the top of the file.
