You're mixing styles a bit. One way is to first assign *out/*object
and then have a common IUnknown_AddRef() at the end of
QueryInterface(). The advantage is mostly that you're saving some code
duplication for the AddRef() and return, although at the cost of
introducing a cast. E.g. d3d10_device_inner_QueryInterface(). The
other style is to AddRef() with the correct interface and return
immediately, e.g. ddraw_surface7_QueryInterface(). I.e., in this case
you'd use "ID3D10Texture3D_AddRef(&texture->ID3D10Texture3D_iface);".
Note that the "else" is redundant if you return.
