It helps a lot when I'm scrolling down the page to look for feature requests, and filter between discussion and those. Anyway if I was being anal I would point out that you didn't bold them.
I don't know if I can implement those, I thought I'd pretty well gotten the 2D functions. But I can certainly check again.
AA functions will require additional, well, functions. There is an _aaline function, but I don't remember it actually doing anything different, and I don't remember there ever being an _aacircle. That may require some icky calculations. Hopefully not. But it will require some extra GL knowledge, which means reading or asking taylor, and either will take time.
ShieldsMax sounds much easier. I'll get started the next time I read this thread and have some time to implement stuff.
