  A still graphics to video generator using gdk-pixbuf
notes: >
  Pixbuf has builtin scaling. It will rescale the originally rendered title to 
  whatever the consumer requests. Therefore, it will lose its aspect ratio if 
  so requested, and it is up to the consumer to request a proper width and 
  height that maintains the image aspect.

parameters:
  - identifier: argument
    title: File
    type: string
    description: >
        The name of a graphics file loadable by a gdk-pixbuf loader. 
        See the output of gdk-pixbuf-query-loaders.
        Definitely png, jpeg, tiff, pnm, and xpm will work.
        
        If "%" in filename, the filename is used with sprintf to generate a
        filename from a counter for multi-file/flipbook animation. The file 
        sequence ends when numeric discontinuity >100.
        
        If the file sequence does not begin within the count of 100 you
        can pass the begin property like a query string parameter, for
        example: anim-%04d.png?begin=1000.
        
        If filename contains "/.all.", suffix with an extension to load all 
        pictures with matching extension from a directory.
        
        If filename contains the string "<svg", then pixbuf tries to load the 
        filename as inline SVG XML, which is convenient for melt commands.
