Vector graphics isn't very nice without anti-aliasing, though. Quality vectors have to be done on a modern CPU or GPU, not with the old Amiga blitter.
I really, really wish Windows and other OSes had the option of using vector icons and stuff. With caching, it's not really that slow. There was some UNIX-type OS a while ago that used vector icons, and did it quickly, but I forgot the name of it.
Here's a decent-looking vector toolkit. At one point, I think someone mentioned that it would be included in a future Amiga OS:
Anti-Grain Geometry
