Description

Interface for outputting frames to an (already allocated) viewer or display.

The viewer is addressed by an "slot" handle, which the client receives from some other public interface. This reflects the fact that is's not up to the client to create an display or viewer; rather they are provided by some internal facility and the client code is handed out an display handle in the course of a larger interaction, like starting a player. This way, when the client code actually is about to produce output, he can allocate the slot and obtain a Displayer (functor) for pushing the frames out. (Users of the C Language Interface have to carry out these steps manually and also have to care for cleaning up and deallocating the slot).

Note: This is a first draft version of a rather important interface. The current version as of 1/2009 just serves a mockup player implementation. You can expect this interface to change considerably if we get at devising the real player.
