// (MSAA + Storage is rarely needed).
// 3. Most features when turned off aren't actually off (we just promise the driver not to use them)
// and it is validation what will complain. This allows us to target a minimum baseline.
//
// TODO: Allow the user to override these settings (i.e. turn off more stuff) using profiles
// so they can target a broad range of HW. For example Mali HW does not have
// shaderClipDistance/shaderCullDistance; thus validation would complain if such feature is used;
// allowing them to fix the problem without even owning Mali HW to test on.
//
// The excluded features are:
// - robustBufferAccess (can hamper performance on some hardware)
// - occlusionQueryPrecise
// - pipelineStatisticsQuery
// - shaderStorageImageMultisample (unsupported by Intel Arc, prevents from using MSAA storage accidentally)
// - shaderResourceResidency
// - sparseBinding (we don't use sparse features and enabling them cause extra internal allocations inside the Vulkan driver we don't need)
// - sparseResidencyBuffer
// - sparseResidencyImage2D
// - sparseResidencyImage3D
// - sparseResidency2Samples
