I left it as critical because IMO it is worth (mine, if no one else's) effort- for 6.x the suggested way to export graphics for presentations or the web* is d.out.file (PNG driver frontend). And currently that means slivers and misaligned polygons. Perhaps I am more "detail oriented" than other people, but to me this really sticks out is a real embarassment that "we can't even get that right". So currently to do this task I wrote a little shell script using xwd|xwdtopnm to take a screenshot of the Xmonitor, which is fine for me and for things smaller than the biggest monitor I can find. [*] (or for reports if you don't mind uglified rasterized plots and ps.map doesn't do it for you) If this was not the primary means of exporting visual images from GRASS I wouldn't be concerned. If I ever find the time I'll work on it, if not I guess it languishes.
