	(using LibTiff 3.4 b37)

	I have a g4 TIFF here that claims to be 1728 x 1055 pixels (this
shows up in the tif->tif_dir.imagewidth and tif->tif_dir.imageheight as well
as tile width and height. also, 1055 is the td_rowsperstrip value and
td_stripsperimage is 1.

	all of this tells me that the image is 1728 x 1055.
	
	but, most image viewers draw this as 1728 x 2110; height doubled.
and, the image looks correct with the doubled height.

	the problem is that i don't see anything obvious in the tif_dir that
tells me to double the height. nor do i see anyuthing in The Gimp or
ImageMagick's TIFF reading code that would do this kind of doubling either.

	can anyone help me out?

	-c
