I've just put up a new example in the d.out.file help page demonstrating
this for the new PS driver.

one trick how to do that nicely: open it at 1200dpi or so, then rescale
down using the rescale tool (Shift-T) + Cubic interpolation. May or may
not give you better results than going to the target size directly from
the File->Open dialog. But you will only lose resoution resampling to
raster, so try hard for a PSutils solution first.
