Fix BESTFIT to work well when pages-per-row > 1.

Browse Source 
There are two causes of the problem:

    - page_ratio should be defined differently

        This is because the usefull page ratio is max_height/total_width
        or max_width/total_height. This then changes accordingly if
        pages_per_row != 1, otherwise, if the pages are of the same
        size, the page ratios will not change, which screws up the
        resizing.

    - Sometimes we need to do height or width division diferently.

        This is because not always total_height or total_width is
        meaningful in BESTFIT condition.

This commit also should fix the bug #0000226.
