[Groff] transparent PNGs?

[Werner LEMBERG]

Gaius,


PNGs created by grohtml have apparently a white background -- isn't it
possible to make the background transparent optionally?

Another suggestion: What do you think about calling the PNG files
<groff_input_file>-<index>.png or something like this?  I can't see an
advantage in the current naming scheme except for debugging purposes
where it may be necessary to stay with the old files.
