Does anyone know of a way of preventing the generation of extra
whitespace around the edge of a figure? The code sample below
demonstrates the problem I'm having - I've tried postprocessing the
postscript output with ImageMagick's "mogrify -trim", but
unfortunately it makes it into a raster image in the process, and I
really need the output to stay in vector postscript.
