pub struct FrameBufferConfigRef {
// some fields omitted
}[EGL 1.0] Reference to frame buffer configuration.
This is not a RAII object, so nothing will be cleaned up when it is dropped.
Instead, the individual methods of this object may return errors if they are used after the display is terminated.
