The "quad-tile" discussion is really about three completely different
things:
1) Testing libtiff to see if it is working right.
2) A TIFF conformance reference suite which can be used to help
verify that any conformant application meets some baseline.
3) A collection of interesting files which represent some of the
things it is possible to do with TIFF.
To date, item #1 has been started as part of continuing libtiff
development, item #3 is already distributed from the libtiff ftp
sites, and Joris appears to be interested in developing #2.
