Re: [PATCH v3 0/27] MR332: include: Fill in missing enum/struct/interfaces in vkd3d_d3d12.idl

[Henri Verbeet (＠hverbeet)]

Just a couple of nits:

Could we make that lower case hexadecimal?

We'd typically use "resource_desc_count" instead of "num_resource_descs" above. There are a couple of other "num_*" parameters in this MR as well. Ultimately I'm not too bothered about these, so don't worry about it if you feel changing them is too much effort, but if you did change them that would certainly be welcome.

Similarly, we'd typically use "dst_descriptor" above and for similar parameters.

I'd suggest something like the following:

```
interface ID3D12Device6 : ID3D12Device5
{
    HRESULT SetBackgroundProcessingMode(
            D3D12_BACKGROUND_PROCESSING_MODE mode,
            D3D12_MEASUREMENTS_ACTION action,
            HANDLE event,
            BOOL *further_measurements_desired);
}
```

We'd typically put the operators at the start of the next line; compare e.g. the existing D3D12_DECODE_IS_ANISOTROPIC_FILTER and D3D12_ENCODE_SHADER_4_COMPONENT_MAPPING macros.
