Splitting the machine generated error structs out to a file allows the values to be updated without changing pngstest.c itself, sine libpng 1.6 and 1.7 have slightly different error limits this simplifies maintenance. makepngs.sh has also been updated to more accurately reflect current problems in libpng 1.7 Signed-off-by: John Bowler <jbowler@acm.org>
