DESCRIPTION
r.out.png exports a GRASS raster map in non-georeferenced PNG image
format, respecting the current region resolution and bounds.
Optionally the user can choose to export a World File to provide basic
georeferencing support. When used with the transparency flag this can
create images useful for KML, TMS, or WMS overlays. (e.g. for use in
Google Earth or as OpenLayers tiles) If output is to stdout, the world
file will be called png_map.wld.
