[mapserver-dev] MS vs GS aesthetics

I may have missed something, but it seems to me from the mapfile that

images pasted in a spreadsheet, and it looks as if there's some
softening coming from somewhere.

there's no possibility yet to set fractional line widths in mapserver.

An area where ms is way ahead of gs is in rendering linear data, as
the gs renderer has some recurrent artifacts, eg
