- Started features to end:

	* Actually use the ucgmpeg configuration window.

	* Compose the videos in other thread to allow showing realtime
	  statistics of the compression (i.e. a progressbar).

- Important features not yet started

	* Add the sound support

	* Add the video & sound mixing support

- Additional features to implement:

	* File streams. For example, streams that read frames from an
	  animated GIF file, or an MPEG/AVI/MOV/whatever.
	  It could be implemented into the constant image stream, changing
	  its name.

	* Motion filter. A filter that allow the images of an stream to move
	  into the animation area between different frames. It should help
	  making cartoons. Of course it needs also its StreamEditor.
