Antialiasing lines mapserver v 4.4.1

[Ken Boss]

Hi Ron--

I don't believe that antialiased lines were supported that far back. 
AFAICT, cartographic symbols supporting antialiased lines and much more
were introduced in 4.6 (see
http://mapserver.gis.umn.edu/docs/howto/cartosymbols/), while a more
straightforward approach to antialiased lines was introduced in 4.8 (see
http://mapserver.gis.umn.edu/docs/faq/antialiasedlines).

HTH,
