Nice work guys, good explanations. I hope this has answered your question Vel, and anyone else who was curious.
There is a further use of antialiasing, which modern graphics cards can do - "FSAA", or Full Screen Anti Aliasing. In its simplest form, this involves creating a double size copy of the entire screen, then shrinking it back down with anti-aliasing, before drawing each frame. This allows the entire screen to have the anti-aliasing effect, but can cause blurriness depending on how it is applied.
