 /*
  This file holds empty Client stubs for use by WebCore.
  Viewless element needs to create a dummy Page->LocalFrame->FrameView tree for use in parsing or executing JavaScript.
  This tree depends heavily on Clients (usually provided by WebKit classes).
 
  This file was first created for SVGImage as it had no way to access the current Page (nor should it,
  since Images are not tied to a page).
  See http://bugs.webkit.org/show_bug.cgi?id=5971 for the original discussion about this file.
