InputMethod::SetCoveredBounds() doesn't make a lot of sense without the context
that it's meant for virtual/onscreen keyboard. Can this be renamed to make that
more obvious? Also, what does 'covered screen bounds' mean? The bounds of the
onscreen keyboard? Or the bounds of the occluded region of some window?

Renamed to |SetOnScreenKeyboardBounds|.
