The dirty secret is that it's basically Cairo, a 1990's graphics API, with modern C++ syntax. So all of the work that's happened since then, including HDR color spaces, precise control of swapchain present, dynamic multimonitor support, doesn't exist. I also got a chuckle out of chapter 10, text (basically TBD, like that's not one of the biggest of all possible cans of worms). In fairness, piet is currently missing the fancy stuff too. But I'm hopeful we'll get there, in part because we can afford to break compatibility. (Going deep into the weeds, presentation doesn't belong at the piet level, but, in my stack, at the druid-shell level. I'm working on this, using quantitative measurements of latency and power dissipation. But it's all evidence that this stuff is quite hard, and Titus is absolutely right that putting it in to a language standard is folly)
