FOSS for hardware, maybe FOSH?

I was thinking more of a summary of our history, starting back from around
when I joined, or even earlier. I think it's an interesting story that will
hopefully interest more people in our project.

that particular example is not a good example since both OpenGL and Vulkan
allow rendering to select if back facing, front facing, both, or neither
triangles should be discarded. I'd assume proprietary 3D APIs such as
Direct3D also allow selecting that. What your thinking of is probably
proprietary game/rendering engines that are built on top of OpenGL/Vulkan
such as Unity3D, Source, or others.
