The libraries use one-way dependency chains, and the callbacks reflect 
that. libvkd3d-utils depends on libvkd3d and libvkd3d-shader; libvkd3d 
depends only on libvkd3d-shader; libvkd3d-shader is standalone.

libvkd3d-utils is not a utility library for libvkd3d, but a wrapper 
library to provide direct d3d12 entry points for the libvkd3d and 
libvkd3d-shader functions not otherwise exposed as d3d12 APIs. It also 
provides a few default callback functions meant to be used with libvkd3d 
APIs.
