/*
Parameter Description Value
 
floatX 
Defines the horizontal distance from the border.
- positive numbers.
 
floatY 
Defines the vertical distance from the border.
- positive numbers.
 
layerwidth 
Defines the width of the menu layer.
- positive numbers.

layerheight 
Defines the height of the menu layer.
- positive numbers.
 
halign 
Defines which border floatX should be counted from.
- left,  center, right.

valign 
Defines which border floatY should be counted from.
- top, center, bottom.
 
delayspeed 
Defines the time delay before the layer's position is updated.
If set to 0 (zero) the layer will move to its correct position immediately.
If set to a value the layer will be slightly delayed before moving to its correct position.(Do not set to values beyond 3).
