The libpng packages offer the standard libraries for manipulating
PNG files, a turbo-studly lossless image format.  This is a security
update for the backwards-compatibility 1.2.x version of this library.


NOTE TO MAINTAINERS:

This DLL, cygpng12.dll, is now officially obsolete and there will be
no further updates -- not even to resolve security issues. libpng14
has been available since August 2007 (five years), so it's high time
those applications were recompiled against a more recent API version
(at this time, libpng-1.5.x).  The applications affected are:

   KDE/qt3/libqt3
   plotutils/libplotter2
   ploticus
   ming/libmingw0
   fltk/libfltk1.1
   fltk_gdi/libfltk1.1-gdi
   xemacs
   ImageMagick/libImageMagick1
   bmp2png
   gnubg
   grace
   spamprobe
   libwmf/libwmf027
   X11/xfig
   X11/libAfterImage/libAfterImage0
   X11/XmHTML/libXmHTML0
   hp2xx
   sng

[[ compiled using gcc-4.5.3-3 ]]
