Description Ryosuke Niwa 2011-09-16 15:07:32 PDT 
Per IRC discussion, we should move away from VisiblePosition and use RenderedPosition in accessibility code.

RenderedPosition has the following benefits:
1. It does not canonicalize positions unlike VisiblePosition so we can fix bugs like https://bugs.webkit.org/show_bug.cgi?id=57685
2. It's performant since it doesn't trigger layout or spends time doing canonicalization
