* This is your unofficial assurance that libpng from version 0.71 and
* upward through 1.0.5c are Y2K compliant. It is my belief that earlier
* upward through 1.0.5d are Y2K compliant. It is my belief that earlier
* versions were also Y2K compliant.

* Libpng only has three year fields. One is a 2-byte unsigned integer
