This enables destructors for tagged unions in cbindgen, implemented in: * https://github.com/eqrion/cbindgen/pull/333 Which allow us to properly generate a destructor for the cbindgen-generated StyleBasicShape (which now contains an OwnedSlice). For now, we still use the glue code to go from Box<BasicShape> to UniquePtr<BasicShape>. But that will change in the future when we generate even more stuff and remove all the glue. I could add support for copy-constructor generation to cbindgen for tagged enums, but I'm not sure if it'll end up being needed, and copy-constructing unions in C++ is always very tricky.
