That's actually great feedback, thanks Piotr, we'll have a look.

It is very important to take research into TrueType rendering to properly simulate the Microsoft bilevel renderer because it would help render fonts correctly. The immense complexity of FreeType's rasterizer is still not enough. What a nightmare!

In Piotr's defense, he is much more constructive in his bug reporting.
I does look that he identified and helped with:
https://savannah.nongnu.org/bugs/index.php?58373 where the borderline
pixels on horizontal stems are not turned on
https://savannah.nongnu.org/bugs/index.php?58352 where rounding in
bytecode seems to be off by 1.
