Added runtime selection of MMX features. Revised makefile.netbsd and makefile.macosx, added makefile.darwin.
Added png_set_strip_error_numbers function and related macros. Revised example.c to provide more details about using row_callback().
Enabled user memory function by default.
Increased png_mng_features flag from png_byte to png_uint_32.
Bumped shared-library (so-number) and dll-number to 3.
Updated makefile.ibmc, makefile.gcmmx
Added some typecasts to eliminate gcc 3.0 warnings. Changed prototypes
of png_write_oFFS width and height from png_uint_32 to png_int_32.
Updated example.c
Revised prototypes for png_debug_malloc and png_debug_free in pngtest.c
Revised pnggccrd.c to conditionally compile some thread-unsafe code only
when PNG_THREAD_UNSAFE_OK is defined.
Added tests to prevent pngwutil.c from writing a bKGD or tRNS chunk with
value exceeding 2^bit_depth-1
Removed restriction that do_invert_mono only operate on 1-bit opaque files
Replaced calls to fprintf(stderr,...) with png_warning() or png_debug()
in pnggccrd.c
Fixed contrib/gregbook/rpng-x.c, rpng2-x.c to avoid crash with XFreeGC().
