Steve Underwood c6f6732231 Fixed a vulnerability in T.4 and T.6 processing which is similar to
http://bugzilla.maptools.org/show_bug.cgi?id=2297
in libtiff. A really screwed up 2D T.4 image, or a maliciously
constructed T.4 2D or T.6 image should potential run off the end
of an image decoder buffer.
