Re: [ft-devel] autohinter for LCD

Uh, doesn't that just do "light" hinting on the x-axis? E.g. adjust the
outer edges of vertical stems to the pixel grid without changing stem
width? That would be compatible with the description of
FT_LOAD_TARGET_LCD. I don't think the autohinter can actually hint for
mono display.

How about altogether removing hinting of vertical stems? ;) I think
LIGHT should be the overall default, but I guess you'd break existing
assumptions in client code. Maybe something for FreeType 3.0.0.

I suspect this is just how things turned out historically.
