I do not support any hinting as it would require ambedding a font
interpreter into the browser. And font interpreter is too complicated
thing to ever work reliably. Second, making a new PNG is easy (you just
take GIMP). I don't know how to make new glyph in TT and existing fonts
are usually copyright-burdened so they are useless.

I have been designing the antialiasing myself and assure you, it isn't
"designed against white background". It generates a resampled alpha mask
which is then used to combine foreground and background color.

There are no smoothing grey subpixels which mingle with whatever, it
works just as if you printed black letters on a gray paper with infinite
resolution and then took a picture of that with a digital camera.

Wouldn't. You apparently don't understand what antialiasing is.

All pixels are symmetrical on the screen. I don't know what are you
talking about.
