accessibility

[Judson Valeski]

We discussed, briefly, accessibility at the API review meeting today. We used Aaron's posting to .embedding/.porkjockeys as a starting point.

Some questions:
1. Is the general approach that all accessibility functionality occur's application wide (across all windows)? Or are there certain things that need to be changed/toggled on a top-level window basis?
2. Any frame level accessibility needs?

Thanks,
Jud
