aVerticalLeftToRightBottomToTop was wrong, it mapped from physical to
logical, and it should be the other way around.

In practice this means that when SwTextFrame::AdjustFrame() is invoked
for a second lower, then nAdd will be a small positive (and not a large
negative) number, so the

warn:legacy.osl:20827:20827:sw/source/core/text/frmform.cxx:479: Ey

warning goes away and the second lower becomes visible.
