OpenGL 3.1 on Asahi Linux

When Vulkan drivers are ready maybe the Asahi Linux perhaps also be ready to run some SteamVR apps https://github.com/ValveSoftware/SteamVR-for-Linux/blob/mast...

I'm surprised that Vulkan wasn't the target, which could then have something like Zink layered on top for OpenGL.

This gets mentioned basically every time. The gist is that:

- OpenGL is a much easier target to support, in terms of having a functional desktop. Remember, hardware-accelerated apps have been runnable on Asahi for months now, while Vulkan support is still a while away. - Most of the work being done is common to OpenGL and Vulkan, so it's not exactly a ton of wasted effort.

Zink requires a fairly advanced Vulkan driver, with many complex optional extensions. A basic Vulkan driver wouldn't cut it. So getting basic OpenGL working is much less work, especially since they can share a lot of work with Mesa's existing OpenGL drivers.
