[New Multicolumn] Use the return value from flipForWritingMode().
flipForWritingMode() comes in at least two flavors; one that takes a
LayoutRect& and one that takes a LayoutSize&. The one that takes
LayoutRect puts the result in the reference passed (and returns nothing).
The one that takes LayoutSize leaves the reference passed untouched
(after all, it's const) and returns the result. Not confusing at all.
Better not ignore the returned value when using the LayoutSize version.
