* The program will report "FAIL" in certain legitimate cases:
* 1) when the compression level or filter selection method is changed.
* 2) when the maximum IDAT size (PNG_ZBUF_SIZE in pngconf.h) is not 8192.
* 3) unknown ancillary chunks exist in the input file.
* 3) unknown unsafe-to-copy ancillary chunks or unknown critical chunks
* exist in the input file.
* 4) others not listed here...
* In these cases, it is best to check with another tool such as "pngcheck"
* to see what the differences between the two files are.
