 Testing ./pngtest.png:
   Text compression[0]=-1

 stereo mode = 1
 vpAg = 100 x 100, units = 0

   Text compression[0]=0
 eXIf type MM, 52 bytes

 Image width = 91, height = 69

Files ./pngtest.png and pngout.png are different
   Was ./pngtest.png written with the same maximum IDAT chunk size (8192 bytes),
   filtering heuristic (libpng default), compression level (zlib default),
   and zlib version (1.2.11)?

 FAIL
