C++ API documentation?

I’ve setup the build tools, compiled the boilerplate example and got it to run. I’ve been looking for something like the PicoSystem’s API cheatsheet listing all API calls for the 32blit with their parameters and what they do but I can’t find one. What documentation is there for the 32blit API?

There’s automagically generated docs at 32blit API: Main Page ; I’m not sure there’s much in the way of human-written stuff beyond the (fairly comprehensive) examples, but it would be quite nice to pull together a basic cheatsheet overview type thing…
