Issue

The Vulkan 1.3 triangle example doesn't exactly need Vulkan 1.3 API. You can lower the API requirement (for physical devices) to 1.0, and enable khr_dynamic_rendering in DeviceExtensions.

When I made this, I wanted to avoid complicating the example code (since it's meant as an introduction). But maybe you're right, it should work with khr_dynamic_rendering too.

I guess if you rephrase it as "triangle using dynamic rendering", you can say it requires Vulkan 1.3 or the dynamic rendering extension.
