Correct.

The command writes its output to $GRASS_PNGFILE.

If the language provides a means to set the environment for individual
commands (e.g. execve() in C, "GRASS_PNGFILE=foo.ppm d.whatever" in
Bourne shell), you can use that, otherwise you need to set it before
calling the command (or just use the same filename each time and
rename the file(s) when the command completes).
