+<p>{des3:79} Rotation is specified in degrees, taken as 0 if the field is not
+specified. Zero means horizontal text, positive degree is CCW rotation around
+x1, y1.

 <p>{des3:36} The horizontal alignment is considered only for multiline text where
 the width of the bounding box matches the width of the widest text line. This
 property determines how to handle the narrower lines. Word-justified means
