-  Eliminated PNG_1_0_X and PNG_1_2_X macros.
-  Removed deprecated functions png_read_init, png_write_init, png_info_init,
-    png_permit_empty_plte, png_set_gray_1_2_4_to_8, and removed the
-    deprecated macro PNG_MAX_UINT.
-  Moved "PNG_INTERNAL" parts of png.h and pngconf.h into pngintrn.h
-  Removed all  WIN32_WCE #ifdefs except those involving the
-    time.h "tm" structure (Cosmin)
-  Reduced dependency on C-runtime library when on Windows (Simon-Pierre)
-  Replaced sprintf() with png_sprintf() (Simon-Pierre)
-  Revised makefiles to avoid making links to libpng.so.*
-  Added a note in libpng.txt that png_set_sig_bytes(8) can be used when
-    writing an embedded PNG without the 8-byte signature.
-  Updated scripts/pngos2.def, pngw32.def, and projects/wince/png32ce.def
-  Added PNG_NO_GET_INT_32 and PNG_NO_SAVE_INT_32 macros.
-  Scripts/libpng.pc.in contained "configure" style version info and would
-    not work with makefiles.
-  Increased sprintf buffer from 50 to 52 chars in pngrutil.c to avoid
-    buffer overflow.

-    pngtest now produces, and made some cosmetic changes to pngtest output.
-    sCAL = 0.352778e-3 x 0.352778e-3 meters, in pngtest.png (Cosmin).

-  Make the 'png_jmpbuf' macro expand to a call that records the correct
-    longjmp function as well as returning a pointer to the setjmp
-    jmp_buf buffer, and marked direct access to jmpbuf 'deprecated'.
-    (John Bowler)
-  Changed "/255" to "/255.0" in background calculations to make it clear
