Providers can use this function to add proposals to the completion. They can do so asynchronously by means of the finished argument. Providers must ensure that they always call this function with finished set to true once each population (even if no proposals need to be added). Population occurs when the gtksource.completion_provider.CompletionProvider.populate function is called.
