-			 *
-			 * When does it work, and how?
-			 * You have to be in fullscreen mode _and_ have auto-zoom turned on.
-			 *   "feh -FZ --zoom 130 imagefile" will do the trick.
-			 *        -zoom percent - the new switch.
-			 *                        100 = orignal size,
-			 *                        130 is 30% larger.
