Hello Cyrille,

Cool ! I didn't know this method with [alpha] and [polygon_smooth].
I get good results here with this method, better than render 4 times a
primitive and translate it by 1/2 pixel with alpha.
Maybe it depends on what you need to render ?
Thanks to this info, my computer will be cooler :)
