FBO Multisampling

I was using pBuffers in OpenGL when FBOs were coming around. Moving to FBOs seemed like a huge increase in simplicity and functionality. I started using them all the time. However, I have always wanted to add a little bit of anti-aliasing, but never quite knew how.

Sometimes googling for OpenGL functions returns pages of garbage and spec files don't always provide clear examples to use. Well, I have found a web page of someone who has had the same problems and has posted his solution including the setup, blitting, etc.

Normally I wouldn't post a blog on a code snippet, but I think this deserves another link so more people will run across this little OpenGL gem.

Thanks, Stefan!
