HarfBuzz Hackfests

Major HarfBuzz development, specially the South / South-East Asian shaper, has happened in HarfBuzz Hackfests, intense week-long pair-programming hackathons between ?BehdadEsfahbod and ?JonathanKew. We have found that these intense hacking events are a very productive way to develop HarfBuzz, and as such looking to continue them. Here's a timeline:
