Apparently the TIFF size limitation is 2**32 bytes in length which is 4GB. It
seems like I have seen TIFFs greater than 6GB but only the file. Never seen them
visually. This does not really help you beyond one aspect. The Version 6 TIFF
specification seems to indicate you are limited to a 4GB TIFF.  Or maybe Im
entirely off in left field.
