Re: [PATCH v2 0/1] MR127: vkd3d: Add an internal reference to a heap when a resource is placed there.

What I'm missing in this patch/MR is:
  - Why do we need an internal reference count here instead of e.g. using ID3D12Heap_AddRef()? It turns out that we have a test that shows creating a placed resource doesn't increment the publicly visible reference count, but I had to go look that up.
  - Why can't we have a test for this?
