I'll push fixes to the review comments as follow-up patches. In the event that this finds approval in the end, I'd squash them into one, if that's okay.

Proof ;)

@tronical oh, could it work in qemu setup or only vmware specific? Or where you using gpu passthrough for that?

I'm using VMware's D3D drivers, those I think do pass-through to some extent. But in principle this should work absolutely anywhere, as D3D comes with the WARP software renderer. I think/hope that Angle falls back to selecting that if no other was found. Otherwise the angle extensions also allow to explicitly select a warp D3D device. This could be an interesting glutin API extension in the future.

Toolkits that use Warp often have some environment variable that allows users to explicitly opt into using warp.

Formatting fixed and squashed.

Thanks!
