 * Plugin Commands are as below:
 *
 * picture_gallery : open the CG Scene
 * 
 * enable_picture [ID] : Add picture to the CG Scene
 * disable_picture [ID] : remove Picture from ID Scene
 *
 * add_sabun [ID] [last ID number]: Add variation to a pic. Basically it means when you choose a pic, you can press confirm to see the next variation
 * 
 * Other Notes:
 *
 * Have a file with File Name + bak  (ex:Gallery_bak.png) to set background to the scene
 *
 * Example
 * After command 
 * enable_picture 3
 * then
 * add_sabun 3 4
 * to have 
 * Pic 3 as Thumbnail and 1st enlarged picture, then display Pic_3_1.png～Pic_3_4.png in order.
 * You can also use "add_sabun_single 4" to load 1 variation only. (in this case, 3_1~3_3 will be skipped, and the transition will be 3 → 3_4)
 * If Split ThumbNail is set to true, ThumbNail will be Pic_3.png, but the first picture after enlarging will be Pic3_0.png instead.
