Hi!

I finished writing the new patch.
It supports fitting image to window in DocViewMode.
It works even if you set a slices.

Thank you for your advice.
I checked the point.

Now it works even with PDF/PS in Japanese!
I found the cause of previous problem in a code I edited.

Please test it and hopefully tell me good results!
Thanks,
