 * This is a little different to the tests shipped with EGL implementations,
 * which wrap the entire thing in #ifndef EGL_WL_bind_wayland_display, then go
 * on to define both BindWaylandDisplay and QueryWaylandBuffer.
 *
 * Unfortunately, some implementations (particularly the version of Mesa shipped
 * in Ubuntu 12.04) define EGL_WL_bind_wayland_display, but then only provide
 * prototypes for (Un)BindWaylandDisplay, completely omitting
 * QueryWaylandBuffer.
 *
 * Detect this, and provide our own definitions if necessary.
