(Apologizes in advance for the slight jaggies in the near field, which need a higher point size for the nearer glyphs, beyond the scope for this demo.)

This seems like a high quality font to me, including the hinting. In orthogonal, pixel for pixel rendering the effect of hinting is more dramatic of course but I think it improves the quality of even the perspective case. I noticed one odd and most probably undesirable behaviour: the hinting algorithm may move the end point but not the interior control point of a quadratic Bezier hull, resulting in an S-shaped artifact in the smooth outline. This can't be good for rasterizing. I doubt it is an error in my outline generator, but of course it could be, and I am not 100% sure whether the issue comes from the font hints or the hinting engine, but it looks like the latter to me.
