Sample image for the latest version of the Unix frontend patch,
see p.unofficial.patches (same subject) for details.  The POV-Ray text
streams are colored and formatted according to the following settings:

export POV_STREAM_COLORS="status=01;47:statistic=35"
export POV_STREAM_FORMATS="all=POV> %s <POV:status=STATUS> %s <STATUS"

	In the top part, a test render (manually stopped) shows that the
streams are wrapped according to the terminal width.  In the bottom part,
the same render is ran again with the standard error piped to the grep
unix command to select only the status line.  Note that in this case the
wrap with is automatically set to 80 caracters (the terminal size cannot
be detected anymore).
