// GMPInit
// - Called once after plugin library is loaded, before GMPGetAPI or GMPShutdown are called.
// - Called on main thread.
// - 'aPlatformAPI' is a structure containing platform-provided APIs. It is valid until
//   'GMPShutdown' is called. Owned and must be deleted by plugin.

// GMPGetAPI
// - Called when host wants to use an API.
// - Called on main thread.
// - 'aAPIName' is a string indicating the API being requested. This should
//   match one of the GMP_API_* macros. Subsequent iterations of the GMP_APIs
//   may change the value of the GMP_API_* macros when ABI changes occur. So
//   make sure you compare aAPIName against the corresponding GMP_API_* macro!
// - 'aHostAPI' is the host API which is specific to the API being requested
//   from the plugin. It is valid so long as the API object requested from the
//   plugin is valid. It is owned by the host, plugin should not attempt to delete.
//   May be null.
// - 'aPluginAPI' is for returning the requested API. Destruction of the requsted
//   API object is defined by the API.
