tiff.c:847: possible bad if test ?

[dcb]

I just ran the static analysis tool cppcheck over the source code
of libpano13-2.9.18. It said

[tiff.c:847] -> [tiff.c:847]: (style) Same expression on both sides of '||'.

Source code is

    if (metadata->xPixelsPerResolution == 0 || metadata->xPixelsPerResolution == 0)

Maybe

    if (metadata->xPixelsPerResolution == 0 || metadata->yPixelsPerResolution == 0)

might be better code.

Thanks. Fixed in repository.
