CC: Canvas <public-canvas-api@w3.org>
All projects will use a framework: canvas is a low level programming 
API, with any use of it, other than for special demonstration, authors 
will build a framework that they will then use.

Here's a good example of a text input field used with Canvas, without a 
framework:
http://mrdoob.com/123/Water_Type

http://mrdoob.com/lab/javascript/effects/water/02/


The text entry field is hidden on the top left of the screen. Its normal 
behaviors would be obnoxious
if they were placed and sized to match the visible text. Note, Mr Doobs 
implementation is correct
for legacy platforms. Authors can test for legacy platforms by checking 
for the drawFocusRing method.

Given appropriate support, the text entry field would be mapped to the 
correct location
and contained within the canvas subtree, working with drawFocusRing and 
other focus/accessibility APIs.
