This makes interesting reading, as I've been following C++ graphics proposals for a while, and they are one of the inspirations behind piet. I hope for piet to have a role in the Rust ecosystem similar to what Titus envisions - it's certainly not a standard, but hopefully will be the tool people reach for, much like serde is for serialization.
Of course, if I fail, the negative consequences are minor, people just won't use it. By contrast, having bad stuff in a standard library lasts almost forever.
