Updating posters

Posters reload themselves:

• when the map view is laid out
• when the poster is selected
• when a note scrolls into view.
• Posters loading via $PosterURL update if $PosterCSS is changed

Thus, changes to the poster’s data might not be reflected immediately.

The action changed(), allows the designated note—default is the current note—to update itself, allowing a stamp to call the poster to update itself. That is useful if some calculation needs to be done before the poster is displayed.

Changing the $PosterURL or the $PosterTemplate of a poster immediately redraws the poster.
