Re: [PATCH v4 0/1] MR632: vkd3d: Implement d3d12_command_list_OMSetDepthBounds()

[Giovanni Mascellani (＠giomasce)]

A points that might require some more work:
* According to Microsoft docs, NaN values are automatically mapped to zero. I can't quickly find any hint in the Vulkan specs of how NaN values are supposed to be handled, so I would assume that nothing is enforced and we should do the mapping ourselves.
* Vulkan extension `VK_EXT_depth_range_unrestricted` should be detected and enabled to set the bounds freely.
* Conversely, availability of this feature should be advertised with `DepthBoundsTestSupported` in `D3D12_FEATURE_DATA_D3D12_OPTIONS2`.
