set-editor in editor-canvas%

Sets the editor that is displayed by the canvas, releasing the current editor (if any). If the new editor already has an administrator that is not associated with an editor-canvas%, then the new editor is not installed into the canvas.

• (send an-editor-canvas set-editor edit redraw?) -> void
     edit : text% or pasteboard% object or #f
   redraw? = #t : boolean

  If redraw? is #f, then the editor is not immediately drawn; in this case, something must force a redraw later (e.g., a call to the on-paint method).

  If the canvas has a line count installed with set-line-count, the canvas's minimum height is adjusted.
