==================== Summary ====================

Name: Graphics-pre.424
Author: pre

Ancestors: Graphics-pre.423

Refactors the embedded object callback to allow for handling cases in which several TextAnchors are attached to the same character. Also allows TextAnchors to change the style of the text by letting TextAnchors work on the scanner (as other TextAttributes are allowed to do).
