I played around with anti-aliasing (thanks jessie), and I'm really
liking it. Take a look at the 2 examples below; the crappy-looking
pictures are non-antialiased, the beautiful pictures are antialiased.
Not that I'm trying to bias your interpretation or anything.
In fact they look so beautiful, I'm thinking its worth sending a picture
to my mum.
Unfortunately, there are two draw-backs -
1. it takes about 3 seconds to draw the non-antialiased image, and about
5 seconds to do the antialiased version.
2. the resulting antialiased image is about twice the size as the
non-antialiased (that means twice the internet transit time)
I'm thinking of making this a server-level default for geoserver, with
an option on the config pages. This should be really easy to do.
Ideally, I'd like to see this as an option in the SLD file or a
layer-specific configuration somewhere. Both of these are not trivial.

ps. We should consider turning antialiasing on by default (its currently
off by default) since the images are so much nicer. Perhaps we should
talk about it/vote at the next Monday meeting?
