Restored png_flush(png_ptr) at the end of png_write_end(), that was removed from libpng-1.0.9beta03. Merged some cosmetic whitespace changes from libpng-1.4.0beta19. Inline call of png_get_uint_32() in png_get_uint_31(), as in 1.4.0beta19. Added demo of decoding vpAg and sTER chunks to pngtest.c, from 1.4.0beta19. Changed PNGMAJ from 0 to 12 in makefile.darwin, which does not like 0. Added new private function png_read_chunk_header() from 1.4.0beta19. Merge reading of chunk length and chunk type into a single 8-byte read. Merge writing of chunk length and chunk type into a single 8-byte write. Moved local array "chunkdata" from pngrutil.c to the png_struct, so it will be freed by png_read_destroy() in case of a read error (Kurt Christensen). Change "purpose" and "buffer" to png_ptr->chunkdata to avoid memory leaking. Change "chunkdata" to "png_ptr->chunkdata" in png_decompress_chunk(), and remove chunkdata from parameter list. Put a call to png_check_chunk_name() in png_read_chunk_header(). Removed two calls to png_check_chunk_name() occuring later in the process. Added a call to png_check_chunk_name() in pngpread.c Relocated a misplaced "#endif /* PNG_NO_WRITE_FILTER */" in pngwutil.c Changed "-Wall" to "-W -Wall" in the CFLAGS in all makefiles (Cosmin Truta) Declared png_ptr "volatile" in pngread.c and pngwrite.c to avoid warnings. Enclose "volatile" declarations in #ifdef PNG_SETJMP_SUPPORTED (Cosmin). Added code in pngset.c to quiet compiler warnings.
