To use PostScript for an image, specify image type @code{postscript}.
This works only if you have Ghostscript installed. You must always use
these three properties:
@table @code
@item :pt-width @var{width}
The value, @var{width}, specifies the width of the image measured in
points (1/72 inch). @var{width} must be an integer.
@item :pt-height @var{height}
The value, @var{height}, specifies the height of the image in points
(1/72 inch). @var{height} must be an integer.
@item :bounding-box @var{box}
The value, @var{box}, must be a list or vector of four integers, which
