We've used private pointers like that in the past in some cases, and
we've generally moved away from them because void pointers just aren't
great to work with. I'd much prefer a scheme like the following:

    struct texture
    {
        ...
    };

    struct d3d11_texture
    {
        struct texture t;
        ...
    };

    struct d3d12_texture
    {
        struct texture t;
        ...
    };

and then using CONTAINING_RECORD to get e.g. a struct d3d12_texture
pointer from a struct texture pointer, much like we do in various
other places.
