2fda9341 - Add virtual buffer backend which allows for experimentation with new browsers supporting MSAA such as Google Chrome and Opera.

Add virtual buffer backend which allows for experimentation with new browsers supporting MSAA such as Google Chrome and Opera. This backend is *very* basic and only renders content using accName and accValue. It does not handle events, meaning dynamic content is not supported. Also, because there's no way to get the ID of a node using MSAA alone, you cannot activate controls and the buffer cursor is not synchronised with the focus and vice versa. Currently, this backend will be used when a Google Chrome document is detected. You will need to specify --enable-renderer-accessibility on chrome's command line to use this. This is very experimental code meant for developers only. No support whatsoever will be provided for using it and no user questions will be answered. You have been warned.
