Wgpu: [Investigation] DX11 examples not working correctly

[Napokue]

When inputting [1, 2, 3, 4] into the compute example. It has to output [0, 1, 7, 2]. This works for Vulkan and DX12 (I couldn't test Metal). DX11 however, outputs [1, 2, 3, 4] also mentioned in issue https://github.com/gfx-rs/wgpu-rs/issues/47.

I have tested the compute examples in Wgpu-rs, Wgpu, and Gfx. Both Wgpu-rs and Wgpu are outputting [1, 2, 3, 4] when using DX11, but Gfx is correctly outputting [0, 1, 7, 2] for DX11, DX12, and Vulkan.

I will investigate and fix this.

I took a look at the cube example on dx11, and it's not working either. I think the memory management needs to be refined there, but I haven't got all the details. TL;DR: this might not be an isolated bug in DX11 but rather a chunk of logic missing.

As of the latest gfx-backend-dx11 release, all the wgpu examples should work correctly on dx11 🎉
