Note Tags
============================================================================

To use fog like RPG Maker XP,
Make sure that sets up the note tags in event editor, as follows.

<fogId:1>
<fogName:001-Fog01>
<fogOpacity:64>
<fogZoom:100>
<fogBlend:20>
<fogSX:1> - if the positive value is, it will move to left.
<fogSY:1> - if the positive value is, it will move to up.
<fogSwitchId:1>
<fogVariableId:1>

all images must be placed in img/fogs folder.

Blend type 20 means a subtract blend.
Once created, the fog image will not be removed until the map is changed.

if switch #1 is ON, the fog will show up on the screen.
