Description

Implementation of Displayer Service, exposed as a public interface.

This service allows to set up display slots, which can be handed over to client code in the course of the play process for outputting frames.

Deprecated:

This is a first draft as of 1/2009, and likely to be superseded by a better design, where rather the provider of an output facility registers with the OutputManager in the core.
