/**
 * Internal implementation to add an image (a world map, though other image data is also fine) to a slide.
 *   Preserves the original image's aspect ratio, leaving blank space below and to the sides of the image.
 * @param slide the slide to add to./*from  w w  w  .  j  a v a  2 s  . c  o  m*/
 * @param anchor bounding rectangle to draw onto, in PowerPoint coordinates.
 * @param picture the picture data.
 * @param markers an array of markers to draw over the map.
 * @param polygons
 * @return the picture shape object added to the slide.
