+ TextAnchors support anchoring of images in text. A TextAnchor exists as an attribute of text emphasis. Depending on whether its anchoredMorph is a Morph or a Form, it repositions the morph, or displays the form respectively.  The coordination between composition, display, and selection can best be understood by browsing the various implementations of placeEmbeddedObjectFrom:.

- TextAnchors support anchoring of images in text.  A TextAnchor exists as an attribute of text emphasis, and it gets control like a FontReference, through the emphasizeScanner: message.

+ In the morphic world, you can embed any form or morph in text by adding a startOfHeader character and adding the TextAnchor attribute to it.
- In the morphic world, simply embed any form or morph in text.

- In this case you select a piece of the screen, and it gets anchored to a one-character text in the editor's past buffer.  If you then paste into some other text, you will see the image as an embedded image.!
