sw clearing breaks: initial layout support
- add a SwTextFly::GetMaxBottom() to know which fly frame has the
largest bottom position from the current paragraph
- add a SwBreakPortion::m_eClear to track if the break portion is a
clearing break
- consider height of breaking clear portions in SwLineLayout::CalcLine()
- increase the break portion height in SwBreakPortion::Format() if this
is a clearing break and we have a fly frame that has a large enough
bottom position, so the next line can "jump down", below the fly frame
(so the line can be full width, which is the whole point of a clearing
break)
