If I change Page::setPageScaleFactor to use view->setScrollOffset instead of view->setScrollPosition, and WebViewImpl::applyScrollAndScale to use setScrollOffset instead of ScrollBy, we can avoid the compositor triggering the 'programmatic' scroll FrameView::setScrollPosition.

setScrollPosition looks like it is updating scroll bars, before calling setScrollOffset. I tried it in Chrome on Android, and scroll bars seemed to be updated OK, however.
