Anti Aliasing

[Pericles S. Nacionales]

Two things you can try...
1. define two layers--one for polygon without outline color with 
transparency set to whatever number, and the other layer defined as line 
and with transparency set to alpha.
2. Create two styles within the layer--1 for the polygon fill with 
transparency set to whatever value you want, 1 for the outlinecolor with 
transparency alpha.

I haven't tried the second one so I don't know if it works. ;)  Make 
sure the line layer (or the outline style) is drawn on top.  If you 
don't want the lines, then I don't know the answer.
