QTiffIO appears to not be portable. I am reluctant to
do much with the code since it belongs to someone else.
There is another project named TiffIO that does
basicly that same thing as QTiffIO and the author
claims it works on all platforms that support QT. He
claims to use it on a daily basis on Windows and I have
done some basic tests on Linux. Need to investgate and
decide if LPROF should switch from QTiffIO to TiffIO
fro tiff support.
