[R] windows focus and setting active device

[ripley@stats.ox.ac.uk]

On R for Windows, you can give focus (as you define it) to a window with
bringToTop(). If you want anything else, you will need to code it
yourself. Beware that this is tricky as the SDI and MDI interfaces behave
differently, as do some versions of Windows.

BTW `highlighted' and `brought to top' are different concepts and
can happen independently.

But not to have it on top.
