Thanks. I was pretty sure I missed something although I did read the
Fine Manual before asking... Maybe the GRASS_PNG_READ description
could be enhanced by adding
Otherwise the GRASS_PNGFILE file content is overwritten each time
a new display command is used.
Also I think that the Example should also set
otherwise it doesn't really make sense as the elevation raster will not
appear on map.png.
