* @plugindesc display foreground tiling sprite(Ver1.0.1)

* @noteParam fgName
* @noteRequire 1
* @noteDir img/parallaxes/
* @noteType file

*
* @help This plugin does not provide plugin commands.
*
* 'foreground' is like a parallax that displays over the map.
* put bitmap file at img/parallaxes.
*
* Map Note:
* write down following 5 settings at map's note.
* <fgName:name> name is the string, file name of tiling sprite.
* if the name starts '!', it is regarded as "foreground zero".
* the filename is searched from img/parallaxes.
* <fgLoopX:number> number is the flag of loop x. 0:no 1:yes
* if this is not written on the note, it'll be 0(=no).
* <fgLoopY:number> number is the flag of loop y. 0:no 1:yes
* if this is not written on the note, it'll be 0(=no).
* <fgSx:number> number is x scroll speed.
* when it doesn't loop x, this is ignored.
* if this is not written on the note, it'll be 0.
* <fgSy:number> number is y scroll speed.
* when it doesn't loop y, this is ignored.
* if this is not written on the note, it'll be 0.
*
* Ex.
* <fgName:sample1><fgLoopX:1><fgLoopY:1>
*
* <fgName:!sample1>

* @plugindesc マップに合わせてスクロールする近景の設定(Ver1.0.1)
* @author 神無月サスケ (thanks to Yoji Ojima)
*
* @noteParam fgName
* @noteRequire 1
* @noteDir img/parallaxes/
* @noteType file
* @noteData maps
*
* @help このプラグインにプラグインコマンドはありません。
* 近景(foreground)は、マップの上に表示される遠景のようなものです。
* 使用する画像ファイルは、img/parallaxes に置いてください。
*
* マップのメモ:
* 以下の5項目を書いてください(設定項目は、遠景と似ています)。
* <fgName:ファイル名> 前景として使うファイル名です（拡張子なし）
* 名前が '!'で始まる場合、遠景同様視差ゼロとなります。
* ファイルは img/parallaxes に置いてください
* <fgLoopX:数字> X座標にループするかどうか (0:no 1:yes)。
* 省略時は0(=no)になります。
* <fgLoopY:number> Y座標にループするかどうか (0:no 1:yes)。
* 省略時は0(=no)になります。
* <fgSx:数字> X座標のスクロール速度です
* X座標にループしない場合は無視されます。
* 省略時は0になります。
* <fgSy:数字> Y座標のスクロール速度です
* Y座標にループしない場合は無視されます。
* 省略時は0になります。
*
* 例：
* <fgName:sample1><fgLoopX:1><fgLoopY:1>
* sample1.png が前景になり、斜め上にループします。
*
* <fgName:!sample1>
* 視差ゼロで!sample1.png が表示されます。
