// Intel Iris Pro 5200, Apple M1)
// MacOS Metal:
// - AMD, Nvidia, Intel GPUs: Shaders are keyed on vertex layout and whether or not
// dual source blend is enabled. That's it.
// - Apple GPUs: Shaders are keyed on vertex layout and all blending settings. We use
// framebuffer fetch here, so the only blending settings used by ubershaders are the
// alphaupdate and colorupdate ones. Also keyed on primitive type, but Metal supports
// setting it to "unknown" and we do for ubershaders (but MoltenVK won't).
// Windows Vulkan:
// - AMD, Nvidia: Definitely keyed on dual source blend, but the others seem more random
// Changing a setting on one shader will require a recompile, but changing the same
// setting on another won't. Compiling a copy with alphaupdate off, colorupdate off,
// and one with DSB on seems to get pretty good coverage though.
// Windows D3D12:
// - AMD: Keyed on dual source blend and vertex layout
// - Nvidia Kepler: No recompiles for changes to vertex layout or blend
