fdo#45330 Improving layout of Confirm File Format dialog

Although fdo#45330 was a duplicate of fdo#45117 which was fixed
earlier, this patch makes the layout look better when the button
text is very long, because it resizes the boundary boxes of fixed
text and ruler, too. I've changed the sequence of
the functions in InitSize() and the size calculations.
