Bug: TIFF reading can't handle certain tile size variants

Description
See the attached sample images and screenshots. It looks like
- All strip variants are OK
- Tiles where the tilewidth == the imagewidth are OK
- Tiles where the tilewidth is less than the imagewidth are corrupted, though some visible structure is present; the red and blue channels are less affected than the green.

I ran into this while testing the C++ TIFF reader since I wanted to make sure that the written TIFF images were readable with the Java reader. These were all created with "gm convert" from GraphicsMagick?.
This also applies to images written with the C++ TIFF write tests, but I can't at this point tell if they are 100% correct due to this bug. Some of the tiling variants and pixel formats aren't supported by many other readers, so I can't tell if I'm running into bugs in the other software or in the writer.

Hi Melissa, I attached these to #11335 last week: http://trac.openmicroscopy.org/ome/attachment/ticket/11335/tiling-variants.tar.xz
There's a heck of a lot of valuable data lost due to the attachments vanishing; I really hope we can get them back soon, if possible.
