Go as a shader language: converts Go code to SPIR-V via HLSL

Cogent Core is a free and open source framework for building powerful, fast, elegant 2D and 3D apps that run on macOS, Windows, Linux, iOS, Android, and the web with a single Go codebase, allowing you to Code Once, Run Everywhere (Core). See the Cogent Core Website for more information, including extensive documentation and editable interactive running examples. The website itself is a Cogent Core app running on the web using wasm.

gosl's Issues

Optimization for vulkan1.2 emits a confusing message..

Finally got around to looking at args to glslc and realized we weren't optimizing! Now passing the -O flag.

Now that we are optimizing, if you set the --target-env=vulkan1.2 which is appropriate, it gives a confusing error in the axon test case:

shaderc: internal error: compilation succeeded but failed to optimize: 2nd operand of Decorate: operand BufferBlock(3) requires SPIR-V version 1.3 or earlier
  OpDecorate %Neurons BufferBlock

so using 1.1 for now, but should try to figure this out. also going through the source code to fix the atomic add issue so may have some insight from there.

There is much I don't understand about these decorators and registers and whatnot. Need to read these at some point:

• https://github.com/microsoft/DirectXShaderCompiler/blob/main/docs/SPIR-V.rst

• https://www.saschawillems.de/blog/2020/05/23/shaders-for-vulkan-samples-now-also-available-in-hlsl/

Not doing type inference on NrnV function in axon

e.g., in axon/act.go

		var gknaMed, gknaSlow float32 // note: gosl can't infer types from NrnV function
		gknaMed = NrnV(ctx, ni, di, GknaMed)
		gknaSlow = NrnV(ctx, ni, di, GknaSlow)

should be easy enough to fix. reports an invalid type.

The examples are broken

The examples no longer work with the latest version of vGPU (see the breaking changes here: goki/vgpu@v1.0.31...v1.0.32#diff-ada36f1ee93fda57ce30c89e3e6430275af64541a22c0faf8c50e304029bd251).
