latest updates sent to James Graham based on latest spec. draft)
- Implementation of Canvas 2D API context changes for non Rich Text Editing
scenarios
  - Steps to assess what HTML elements are allowable in the shadow DOM
  - Work effort to decide what is allowable in Canvas Shadow DOM (Canvas
subtree)
  - What are the next steps to address Rich Text Editing in HTML 5?
     - Need to be able to get and set selections to/from contenteditable
areas and input controls
     - need to be able to get and set caret position in these areas
     - Need to be able to ensure text content wrapping in non-visible
shadow DOM
     - Need to be able to acquire grammar and spell checking errors in
content editable areas (these would be ranges)
     - Need a common API for these across browsers
        - Browser API Comparisons for Caret Tracking and Content Selection:
http://www.quirksmode.org/dom/w3c_range.html
        - Getting the selection object:
https://developer.mozilla.org/en/DOM/window.getSelection
        - sel = window.getSelection() //sel is a Selection object
        - rangex = sel(0);
        - rangex.collapsed(); //If it is collapsed it is a  caret
        - reangex.collapse();
     - Need to develop examples
