[OT: <PictureName>,<X>,<Y>,<D> ]

Overlay Transparent

This is identical to the [O: ] command, but uses transparent pictures.

Transparent areas are also copied.  In this manner one can have holes appear in the base picture, a lowered side wall, another load or many other variations.

There are 3 groups of similar modifiers.

The [O: ], [OT: ], [OB: ] modifiers put the overlay picture immediately on the specified position.

The [P: ], [PT: ], [PB: ] modifiers define the place for the overlay picture (usually in a macro definition), the overlay picture will be specified in a following modifier.

The [D: ], [DT: ], [DB: ] modifiers define both the position and the overlay picture (usually in a macro definition), the overlay picture will be placed only at the usage of a following modifier, having to specify only the name of the overlaying, a single word.
