/*:
 * @plugindesc Fixes an issue with large sprites appearing under ☆ passability tiles.
 * @author Neon Black - Version 1.0
 *
 * @help Large Sprite ☆ Fix v1.0
 *
 * V1.0 - 8.11.2015
 *
 * This plugin was created to fix an issue similar to the fix applied in Ace
 * where large sprites would display under ☆ passability tiles when they should
 * appear above them.  This plugin is for the most part non-intrusive but does
 * require a little bit of input from the user.
 *
 * By default, only the player is affected by this plugin.  To apply this fix to
 * an event, add the tag <large sprite> to a comment box in the page of the
 * event you would like to appear above ☆ tiles properly.

 *
 * @param Terrain ID
 * @desc This is the ID of the terrain to fix with ☆ tiles.  Terrain ID is set in the database.
 * @default 7
 *
 * @param Large Followers
 * @desc Enable this option to perform large sprite checking on followers.  Disabled by default.
 * @default No
 *
 * @param Large Vehicles
 * @desc Enable this option to perform large sprite checking on vehicles.  Enabled by default.

 * @author Neon Black - Version 1.0
 *
 * @help Large Sprite ☆ Fix v1.0
 *
 * V1.0 - 8.11.2015
 *
 * このプラグインは、すり抜け可能タイル(★タイル)の上に表示されるべき
 * スプライトが、背面に表示されてしまうバグの修正を行います。
 * ほとんどが自動的な修正となりますが、多少のカスタムが必要となります。
 *
 * デフォルト状態では、このプラグインが有効になるのはプレイヤーに対してだけです。
 * イベントに対してもこのプラグインを有効にしたい場合は、
 * 対象のイベントのコメントボックス内に<large sprite>タグを挿入してください。
 * これによって、★タイルの上にイベントを表示することができます。
