using struct won't give the correct signature
That's why there's `extern(C++, class) struct Image`, see https://dlang.org/spec/cpp_interface.html#classes.
Not sure about the const part too, if this is correct on the D side...
As const is transitive in D, mangling a const object reference as C++ `const T *const` is consistent, but also means that a `const T *` cannot be mapped directly to D via a class (but as `const(T)*` if T is a D struct).
