On the PostScript printers the - picture control line can have a more
general form
 - picture <file.PS>,x,y,kx,ky,z
where the extra (optional) parameters are scaling coefficients kx,ky
and angle of rotation z in degrees. If z is positive, the picture
will first be scaled and then rotated. If z is negative, the picture
will first be rotated and then scaled by angle -z.
Furthermore, x and y can be replaced by relative coordinates of the form *+C
or *-C where C is a constant. The reference level * of y is the base
level of the current line and the reference level * of x is the current
start position of the line (determined by the left margin).
This feature greatly simplifies positioning of (possibly overlapping)
pictures with respect to the current text.
