For backwards compatibility. Newer vkd3d versions may report more
capabilities, but some of those may also require newer vkd3d APIs in order to
use them. That's an issue for a vkd3d user like Wine, where reporting more
capabilities may cause the application to try to use APIs that are not
implemented in that version of Wine.
Note that using ELF symbol versioning would have solved the issue for existing
binaries compiled against older versions of vkd3d, but not for older source
compiled against newer versions of vkd3d.
Users of vkd3d-utils should define VKD3D_UTILS_API_VERSION to the vkd3d
API version they wish to target.
