133 current chunk name is now available in png_struct to reduce the number
136 try to get ready for unknown-chunk callback functions:
137 - previously read critical chunks are flagged, so the chunk handling
138 routines can determine if the chunk is in the right place
139 - all chunk handling routines have the same prototypes, so we will

813 when it tries to read an erroneous PhotoShop iCCP chunk.
907 Revised the iCCP chunk reader to ignore trailing garbage.
992 Check for missing profile length field in iCCP chunk and free chunk_data
993 in case of truncated iCCP chunk.

1290 Changed sPLT failure action from png_error to png_warning and abandon chunk.
1310 duplicate chunk types to go undetected.
1359 Fixed bug with sCAL chunk and big-endian machines (David Munro).
1591 after another intervening chunk type.
1627 Fix potential buffer overflow in sPLT chunk handler.
1715 Added png_ptr->unknown_chunk to hold working unknown chunk data, so it
1716 can be free'ed in case of error. Revised unknown chunk handling in

1745 instead of key in zTXt chunk (Kevin Ryde).
2038 Fixed bug with unknown chunk handling, introduced in version 1.2.17rc2

2264 to avoid memory leak after memory failure while reading tEXt chunk.`
2380 Relocated misplaced #endif in pngwrite.c, sCAL chunk handler.
2407 multiple times and to specify the sample order in the tRNS chunk,
