Description Constructing a cube view of a depth buffer, e.g. for sampling for shadows appears to hit an unimplemented! in the dx12 backend of gfx-hal
unimplemented!

Repro steps Create a texture with:
let point_shadow_tex = wgpu::TextureDescriptor { label: None, size: wgpu::Extent3d { width: diag_two_size / 4, height: diag_two_size / 4, depth_or_array_layers: 6, }, mip_level_count: levels, sample_count: 1, dimension: wgpu::TextureDimension::D2, format: wgpu::TextureFormat::Depth24Plus, usage: wgpu::TextureUsage::SAMPLED | wgpu::TextureUsage::RENDER_ATTACHMENT, };
And create a view with:
let point_shadow_view = wgpu::TextureViewDescriptor { label: None, format: Some(wgpu::TextureFormat::Depth24Plus), dimension: Some(wgpu::TextureViewDimension::Cube), aspect: wgpu::TextureAspect::DepthOnly, base_mip_level: 0, level_count: None, base_array_layer: 0, array_layer_count: None, };
