The GenericFramebufferConsoleImpl class implements the logic without taking into account any other details such as synchronization. The GenericFramebufferConsole class then is a simple wrapper around GenericFramebufferConsoleImpl that takes care of synchronization. This allows us to re-use this implementation with e.g. different synchronization schemes.
