> No, it's evident that both are glitchy. You can't arbitrary say one renderer but not the other does it "quite well" when both have many errors. They are both extremely glitchy, and that's exactly the implementation nightmare. 

There is an international agreed ISO standard, ISO 14496-22, currently at its 4th edition, about fonts. It is quite possible to say one renderer is more compliant than another. So yours is broken, and more broken than others. That's quite evident.
I fixed some bugs in a development version, which would make the 2.0 version of TD renderer significantly more accurate than 1.0. https://i.imgur.com/oKDg7F1.png I also made sure to research how dropout control works and implement much more accurate rules than in TD renderer 1.0. So the FreeType guys should fix the bugs in their rasterizer as well.
