*
* things to add:
*
* * left and right margins
* * anchors (for inline objects other than text - images etc.) - variable size ones too
* * if a word (or char) doesnt fit at all do something sensible
* * freeze thaw api
*
* tough ones:
* * directly accessible text spans (so you can track where that span is, how big it is after many inserts/deletes) and modify its formatting etc.
* * overflow objects (overflow from this textblock can go into another)
* * directly accessible text spans (so you can track where that span is, how big it is after many inserts/deletes) and modify its formatting etc.
* * on change figure out what node the change is in and figure out what line (nodes) it affects and only modify those nodes on that line or maybe others until changes dont happen further down
* * obstacle objects to wrap around
* * kerning control
