this should be desktop-linux-only. i _think_ that the way to detect that is:

  #if !defined(OS_CHROMEOS) && defined(USE_X11)

but i'm also wondering if is_dragged_tab or something similar would be more
appropriate. are there any cases where we'd have an override-redirect browser
otherwise?

It's:

#if defined(OS_LINUX) && !defined(OS_CHROMEOS)
