Create wld file for map image

It is easy to export a raster file as a georeferenced images with e.g., GRASS, QGIS or gdal. It becomes more complicated if you want to export a map, composed of different layers.

It works like a charm, except for the “any size” part. The function, on my system, does not handle very large image sizes very well.
