 * Hi, I am developing a plugin which uses Fancybox jQuery plugin. For completeness,
   I am including the Fancybox script in the plugin package. However, I don’t want
   to load id from my plugin if it is already loaded by something else.
 * Effectively, I want to make sure that Fancybox isn’t added multiple times.
 * Is there a way that I can find out what scripts are already in the script queue(
   from wp_enqueue_script) in order to prevent loading the script multiple times?

 * if it has been loaded via wp_enqueue_script then it will only get loaded once–
   even if added multiple times.

 * I am not entirely sure that is true. If two different plugins load the Fancybox
   jQuery javascript file but they give it different tags (argument 1 to wp_enqueue_script),
   how would wp_enqueue_script know that it is the same thing?
 * Of course, I as type this, I am realizing that there really isn’t a way to have
   a fool-proof way to get what I want done.
 * I am trying to get around the fact that the Fancybox for WordPress plugin and
   my plugin include two different version of the Fancybox javascript which conflict
   with each other.

 * test it… probably the only way you will know for sure.
