GM_ExportMapLayoutComponent

Exports a component of the currently setup map layout (use GM_LoadMapLayoutFile to load a layout definition) to a bitmap (BMP) file. The bounding box and pixel dimensions that you specify are the same as you would provide to the GM_DrawLayerList function and are used to determine the pixel size that the BMP file will use. If you always call this after a draw, just pass in NULL for the world bounds and 0 for both pixel dimensions.
