 * @help Improve image preloading to eliminate image display lag.
 * 
 * By default， when the event starts， the face images of [Show Text]
 * and the picture images of [Show Picture] in the 200 lines
 * from the beginning of the event are loaded first.
 * This allows the images to be displayed quickly when they are actually used.
 * However， since there is no additional preloading of images appearing after
 * the 200th line， the lag will be noticeable later in the long event.
 * 
 * To solve this problem，
 * this plugin allows you to set the number of lines to preload.
 * When the number is 0， all lines of the event will be preloaded.
 * However， if the event is very long， it may take some time to preload.
 * In addition to the face images of Show Text and the picture of Show Picture，
 * the parallaxe images of [Change Parallax] and the character images of
 * [Change Image] in [Set Movenemt Route] are also preloaded.
 * 
 * You can also use the plugin command "Preload Image" to preload any images.
