  -width=uint set width of the viewport (default is viewer width).
  -height=uint set height of the viewport (default is viewer height).
  -show_console prints the name of the output file in the console.
  -format permits to choose the output format and the tool to produce the file.
  If 'guessed', which is the default, the format is choosen/deduced from the file extension.
  For example for out.png, the format will be inzb_png.
  The known formats are:
    inzb_[ps,png,jpeg] : pixmap of the scene is put in a PostScript, png or jpeg file
  by using the inlib::sg::zb_action.
    gl2ps_[eps,ps,pdf,svg,tex,pdg] : primitives of the scene (vector graphices) is put in an
  encapsulated PostScript, PostScript, PDF, SVG, LaTeX or PDG file by using gl2ps.
  If 'guessed' is used as format, then according to the file extension, the tool used is:
    .ps, .eps: inzb_ps
    .png : inzb_png
    .jpg, .jpeg: inzb_jpeg
    .pdf, .svg, .pgf, .tex: gl2ps_[pdf,svg,pgf,tex]
  Example:
    scene_write_to_paper out.jpeg  # produce a out.jpeg file in current directory by using inzb_jpeg.
    scene_write_to_paper -out_dir -format=inzb_png -scale=2 out.png
    scene_write_to_paper -format=gl2ps_pdf out.pdf
