Content: Remove redundant and unused redraw message fields.

This was archaic support for rendering images as "overlays",
and avoiding a redraw via the browser window redraw and HTML
contents.  Basically it was "plot this image here", but it
was too error prone, so it was removed a long time ago.

These are some last vestiges that made the redraw message
look more complex than it is.
