Not just that, we actually ship Zink with our Vulkan based game because for absolutely insane reasons many years ago the decision was made to expose a GL context to plugins for graphics work. The hardest part was to provide a couple of required extensions and massaging Zink to use our Vulkan device with our extensions and also stub out its memory allocator for ours. Oh, and making sure we get to get dibs on loading opengl32.dll/libgl.so that translates into Zink.

It weirdly sounds crazier than it is. Mike is an absolute legend for all of his work on Zink.
