[GRASS-dev] why d.vect.thematic won't run on WinGRASS - d.mon problem

[Michael Barton]

I'm going to try this as soon as I can steal a bit of time. I'm  
somewhat uncertain how to get the initial PNG for GRASS_PNG_READ.

I can create a dummy temp map using r.mapcalc and then save it to a  
PNG using r.out.png. But I need to make sure that it's background is  
transparent so that the final composite can overlay whatever is in the  
map display. Any suggestion for how I do that?
