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.
