All, thought it'd be helpful to hit reply, so the number and channel are 
easily accessible in your e-mail client.

I've revised the Canvas Rendering Context 2D document that Richard 
attached, in relation to the setCaretSelectionRect proposal,
removing many references to "text". They were not intended for 
implementers. The concept of "selected" is defined in ARIA,
so I hope that using "selection" as a word, has more firm ground. I've 
kept the word "caret" in the proposal.
