8be63adbc8 [master] Relocated various UNKNOWN_CHUNK macro definitions 
outside of the PNG_READ|WRITE_ANCILLARY_CHUNK_SUPPORTED macros and
updated CHANGES and ANNOUNCE.  The definitions were actually relocated

Glenn Randers-Pehrson
bbe589da44 [master] Change some instances of PNG_READ_UNKNOWN_CHUNKS_SUPPORTED 
to PNG_HANDLE_AS_UNKNOWN to make it possible to build a libpng that can
use the png_set_keep_unknown_chunks() mechanism to ignore unused chunks
without having to save unknown chunks.

286467db82 Restored compiling png_combine_row() for progressive readers.

6b60a31ebf Restore png_memset() call 
This stuff should be handled in the APNG fork.

54028e5943 Revert "png_reset_prev_row" from png.h and pngrutil.c 
This should be handled in the APNG fork, not in libpng proper.
 2009-05-18 11:49:19 -05:00
Glenn Randers-Pehrson
0c062e839d Conditionally compile png_combine_row() and png_read_finish_row() 
which are only used by sequential PNG readers.  This can save some
resources in applications that only do progressive reading.

Glenn Randers-Pehrson
e38b432846 Clarified usage of sig_bit as struct vs sig_bit_p as pointer in example.c 
sig_bit was not declared in write_png() and was used differently from
sig_bit in read_png(), as reported by Vincent Torri.  This update changes
sig_bit to sig_bit_p in read_png() and declares sig_bit in write_png().

549a5101e7 Fixed inconsistency in use of "row_bytes" in pngrutil.c

This bug was introduced in libpng-1.2.36.
