As a follow-up to #161 on really old systems.

On my machine, it seems to run through Angle just fine.
However, @DileSoft provided the following logs for his machine:

Turns out, we need to symlink libEGL.so.1 to libEGL.so for Angle to be picked up, actually.
First error is:

INFO: EGL ERROR: eglCreateContext: Unknown attribute: 0x31b2X

This is caused by this code:

        if needs_robustness {
            if version >= (1, 5) {
                log::info!("\tEGL context: +robust access");
                context_attributes.push(egl::CONTEXT_OPENGL_ROBUST_ACCESS);
                context_attributes.push(egl::TRUE as _);
            } else if display_extensions.contains("EGL_EXT_create_context_robustness") {
                log::info!("\tEGL context: +robust access EXT");
                context_attributes.push(EGL_CONTEXT_OPENGL_ROBUST_ACCESS_EXT);
                context_attributes.push(egl::TRUE as _);
            } else {
                log::warn!("\tEGL context: -robust access");
            }

            //TODO do we need `egl::CONTEXT_OPENGL_NOTIFICATION_STRATEGY_EXT`?
        }

So it's not clear to me why it considers the attribute to be unknown. It reports EGL version 1.5, and the specification for egl-1.5 has this enum value...

If we work around it, the next error is:

Looks like there is still an issue on some platforms.
