The comment on the previous line says "// fall-through" , so it is intentional.

That one probably is unintentional, but as you see, harmless anyway.

That one certainly looks like a bug, yes. Have you tested whether
axial gradients indeed end up looking wrong in exported PDF? (Or
perhaps even generate incorrect PDF?)

You mean whether it is normal behaviour for people to make mistakes?
Yes. That's why we try hard to make our code warning-free, i.e. to
compile with -Werror (gcc and Clang) or -WX (MSVC), and use static
analysers. Why the compilers and static analysers have not warned
about at least the last case you mentioned, I don't know.
