 * sure that the graphics state is reset.
 *
 * @param targetPage the target page
 * @param form the form to place
 * @param transform the transformation matrix that controls the placement of your form. You'll
 * need this if your page has a crop box different than the media box, or if these have negative
 * coordinates, or if you want to scale or adjust your form.
 * @param layerName the name for the layer/OCG to produce
 * @return the optional content group that was generated for the form usage
 * @throws IOException if an I/O error occurs
