This comes only when gmerlin has to show some video or still images. It is created and owned by the video output plugin (i.e. it has nothing to do with the core GUI). Currently, only an X11 plugin is available. It has some special features: You can zoom or squeeze the image to make your favourite tradeoff between aspect ratio distortion, black borders or cropped images. All global gmerlin Shortcuts work also in the video window, as well as some special ones.
