Large scanline oriented TIFFs are a pain to work with in my 
experience.  Using tiled TIFFs with TIFFWriteTile() is probably easier 
than using a pseudo-tiling system on top of TIFFWriteScanline().  Of 
course your final processing determines whether you can do that at 
all, but there's my 2c anyway. :)
