antialiasing true/off works well, and what you have to do are:
1. comment your "OUTPUTFORMAT...END"ONJECT, add "IMAGETYPE PNG24"
2. set "TRANSPARENCY ALPHA" in your layer object
3. set "ANTIALIAS TRUE" in style object.
that's all!

Yet apparently rendered line work (which isn't pixmap based) is also
"smoothed"? Is that right?
