Enum GlBackend 

#[non_exhaustive]
pub enum GlBackend {
    Desktop,
    Egl,
    Angle(AngleBackend),
    Web,
}

Which GL context flavour GpuContext::OpenGL::context points at.

Desktop / Egl / Angle(_) distinguish which procedure-loader an interop layer uses (wglGetProcAddress + opengl32.dll, eglGetProcAddress, dlsym on the relevant .framework). Web is reserved for wasm / WebGL2 callers; cross-API interop isn’t reachable there.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.
