Library only supports 1 row per strip with TIFF saver

[postnik0706]

I am comparing results of CCITTFAX4 compression of the same black-and-white 59 KB PNG scan file converted to TIF using TiffBitmapFactory against Imagemagick (Windows platform). TiffBitmapFactory gives a 107 KB file while with Imagemagick it is just 43 KB.
Can that be because NativeTiffSaver.cs seemingly only implementing a 1 row per strip for TIFFS?
Would appreciate any insight.
