OpenGL backend for gfx.
Can only be used on non-Apple Unix systems. The WSI is hard-coded to EGL.
Note: the Instance, Surface, PhysicalDevice, Device, and Queue can only
have their methods called on the thread where Instance was created(!).
Recording command buffers is free-threaded.

- Binding slot (0 ..
