All these hardcoded offsets feel quite fragile to me. Maybe it would be better to use [some technique like this](https://gitlab.winehq.org/giomasce/wine/-/blob/1501bca0da02980a5fa76b3c6c882...) to have the compiler copy around offsets for us.

Just a comment, though, it's definitely out of scope for this MR.
