<p>Render barcode to cairo context. Context should be prepared with desired
translation and appropriate scale. Context should be translated such that
the origin is at the desired location of the upper left hand corner of the
barcode bounding box. Context should be scaled such that all dimensions
are in points ( 1 point = 1/72 inch ) and that positive y coordinates
go down the surface.</p>
