 * -----------------------------------------------------------------------------
 * *) Introduction :
 * -----------------------------------------------------------------------------
 * This plugin allow you to have many texts written on screen.
 *
 * -----------------------------------------------------------------------------
 * *) How to use :
 * -----------------------------------------------------------------------------
 * Write this following line to script call to add text on your screen
 *
 * this.text(key,x,y,text,z,show,width,height,color1,color2);
 *
 * Paramaters that must be filled:
 * - key  >> Is a hash key. You may fill it with numeric or string. It's used to
 *           delete your on screen text later
 * - x    >> X coordinate from top-left
 * - y    >> Y coordinate from top-left
 * - text >> Is the text you want to display on screen. It's support escape
 *           characters such as \N[1] in show text message. But, you have to use
 *           double slash to activate. For example \\N[1]
 *
 * Parameters that can be ommited :
 * - z      >> Z coordinate on screen. The larger number means the closer to
 *             player text will be displayed. If it's ommited, the default value
 *             is 0.
 * - show   >> show duration in frame. If you want to text stay on screen until
 *             you delete it manualy, use -1. The default value is -1
 * - width  >> width of a rectangle that will be used to draw a box
 * - height >> height of a rectangle that will be used to draw a box
 * - color1 >> Color of the rectangle. Must be filled by
 *             'rgba(red, green, blue, alpha)'
 * - color2 >> Second Color of the rectangle. The default value is same as
 *             color1
 *
 * To delete a certain text. Use this script call
 * this.del_text(key);
 *
 * Key is a hash key. Same as above
 *
 * To clear entire screen, use
 * this.clear_texts();
 *
