Change the quirks mode text-decoration code (soon to be used for all modes) to follow CSS 2.1's rules for positioning of decoration lines. Decorations are now drawn at a constant vertical position established by the element creating the decoration, and more than one of the same type (underline, overline, line-through) of decoration are supported on the same piece of text. This means that text-decorations can now significantly overflow a text frame, since the vertical-alignment of the element with text-decoration may be substantially different from the vertical alignment of the text. Set overflow areas for text frames with text decorations in nsLineLayout::RelativePositionFrames since it must happen *after* vertical alignment is done, and when relative positioning data are consistent (nsIFrame::GetRelativeOffset matches the offset that has been applied).
