(comment ```depends on glfw and webgpu, see ./WebGPU-distribution-info.txt and ./glfw/glfw-sources-here. built and "tested" this only on windows so far

todo:
 - need to handle getting webgpu better than a zip file
 - and cloning glfw
 - needs more functions
 - move helper functions request-device/adapter into auxiliary c.file
```)
