 * Version 1.00
 * SumRndmDde
 *
 * By default, the frame around a window stretches the texture used
 * by a custom Window Skin.
 *
 * Using this Plugin, the frame will "repeat" like it did in VX Ace.
 *
 * It's plug-in and play.

 *
 * デフォルトでは、ウィンドウの周りのフレームは、
 * カスタム・ウィンドウ・スキンで使用されているテクスチャを伸張します。

 * このプラグインを使用すると、
 * VX Aceの時と同じようにフレームが「リピート」されます。
 *
 * プラグインを入れるだけで動作します。
