GM_DrawLayerListToMemory

Draws one or more layers to the provided memory buffer at the given location. If aWorldBounds is not NULL, at least the specified area will be drawn. The aspect ratio of the screen pixels will be maintained, so slightly more of the world bounds than specified may be drawn. If aWorldBounds is NULL, the entire specified layer or all of the loaded layers will be rendered.
