Where is subpixel rendering handled?
For those of you who are still curious, I ran across this site, explaining how to turn subpixel rendering on and off for a webpage. Make sure to check out the demo page. I still don't know how it's handled at the OS level, but I'm guessing that to get any farther I'd have to actually learn about how fonts are rendered, and I don't think I'm prepared to do that. It also looks like there is a debate in the community over whether subpixel antialiasing is better than pixel antialiasing. Here is the case for subpixel rendering.
