HLSL Examples

[Cons-Cat]

Like the Sascha Willems Vulkan samples, perhaps Liblava could provide shaders written in HLSL in addition to GLSL. I understand that in this repo's examples so far, the shaders are not the interesting part, but most students and teachers at my school can't even read GLSL, so I think providing examples in both may be beneficial. I personally wouldn't mind practicing porting between the two, so I could make a pull request for this if you think it's a good idea.

I've put the focus on GLSL for now, but there's nothing wrong with offering both if preferred.
