accuracy of sin GLSL function on Intel/AMD/NVidia GPUs:
https://community.khronos.org/t/builtin-math-function-execution-cost-issues-with-accuracy-of-builtins/75130/4

Both AMD and NVidia GPUs are waay more accurate than is required by Vulkan,
another reason I think we shouldn't implement horribly inaccurate functions
just because they technically meet the Vulkan spec.
