The given image has a separate planar configuration (TIFFTAG_PLANARCONFIG ==
PLANARCONFIG_SEPARATE) and is 16bit. For loading 16bit we cannot use libtiff's
convenience methods but use TIFFReadEncodedStrip directly.
Currently we do not support this type of image, I am not quite sure what is the
right way to interpret such tiles.
I found this
http://www.gnu-darwin.org/www001/ports-1.5a-CURRENT/graphics/xpaint/work/xpaint-2.7.8.1/rw/readTIFF.c
file as an example but they read row-by-row and 8bit data. We read
strip-by-strip and 16bit.
