Make it possible to keep track of scrolls

Some platforms may need to keep track of scrolls even if it requires full
repaint of the viewport. For instance, if we have a tiled backing store, we may
repaint the whole viewport, but we still need to move the tiles by the given
offset.

The implemented approach was discussed with David Hyatt on IRC.
