Passing the main struct to the public functions allows us
to share common data between multiple types of operations.

The current code uses D3D12 abstractions to create pipelines but
issues raw Vulkan API calls to actually implement the functionality,
which means the code makes assumptions about the exact descriptor
set layout and push constant layout, which is generally a bad idea
now that we have multiple code paths for root constants etc.
