Ah. I didn't understand what these flags were intended for. That makes
quite a bit of difference.

I spent several days experimenting with different filters; the current
ones work best at 100dpi and above. Lower dpi values present too large a
pixel area, and even the slightest color is quite visible.

to match changes made to the stems For example, in a gothic font it would
be nice to see all of the stroke widths match precisely after hinting.
