Eh, nowadays you're probably rendering on a phone screen with a PenTile display and 300ppi, so the entire thing is moot. Plus, every implementation of subpixel

Eh, nowadays you're probably rendering on a phone screen with a PenTile display and 300ppi, so the entire thing is moot. Plus, every implementation of subpixel hinting I've seen (and I've seen them all, on all three major desktop platforms), produces absolutely disgusting colour fringing. Just lay off the ClearType(tm) kool-aid and do normal anti-aliasing. We don't do colour-fringing anti-aliasing for any other geometric primitive, I see no reason to implement a font-specific approach that only works if the user is colour-blind.
