text_output/continue_note_after_text
Continue note after text: Insert a dot sequence or an arrow image at the end of a Textflow.
Place a Textflow while inserting a dot sequence at the end of each fitbox. Use the "width" key of info_textline() to retrieve the width of the dot sequence. Fit the Textflow with the "createlastindent" option set to the width of the dot sequence to specify appropriate empty space at the end of the fitbox. Then, fill the space between the last word and the right fitbox border with the dot sequence using fit_textline(). For placing the dot sequence use the font and font size of the Textflow by retrieving it with info_textflow() and the "lastfont" and "lastfontsize" options. Similarly, place a Textflow but insert an arrow image at the end of each fitbox.
