Bug Description

The mir eglDisplay exposes EGL extensions that it doesn't actually implement.

Including:
 - EGL_EXT_buffer_age
 - EGL_EXT_swap_buffers_with_damage

Mir claims to support these, but when using them noting is actually painted.
According to Chris, these implementations aren't there yet. In mesa, at least.

Whether we ever use these extensions is a debate for another day. But if we're probing for things we're not using, that's a bug.

Oh I see. We're not probing for these but they are exposed to clients by Mesa.

I finally got around to updating the Mir EGL platform patch in pkg-xorg git; it should now expose correct values for EGL_EXT_buffer_age and not claim support for EGL_EXT_swap_buffers_with_damage.
