// Ozone platforms must override this class and implement the virtual
// GetFooFactoryOzone() methods to provide implementations of the
// various ozone interfaces.
//
// The OzonePlatform subclass can own any state needed by the
// implementation that is shared between the various ozone interfaces,
// such as a connection to the windowing system.
//
// A platform is free to use different implementations of each
// interface depending on the context. You can, for example, create
// different objects depending on the underlying hardware, command
// line flags, or whatever is appropriate for the platform.
