[ANNOUNCEMENT] Updated: libpng-1.4.3-1; NEW: {libpng14/libpng14-devel}-1.4.3-1

[Charles Wilson]

The libpng packages offer the standard libraries for manipulating
PNG files, a turbo-studly lossless image format.  This is a major
update to the libpng-1.4.x series.

[[ compiled using gcc-4.3.4-3 ]]

CHANGES (since 1.2.44-1)
========================
o update to latest official release of libpng-1.4.x
o ABI change upstream so DLL is now provided by the new
  libpng14 package.
o Take this opportunity to switch to the autotool-driven
  build. This results in the rather odd DLL name cygpng14-14.dll.
o Install unversioned files.

FYI, package maintainers:

A number of (obsolete) APIs were dropped from 1.4, meaning that a lot of
packages may not build OOTB with libpng14.  Here is a summary of the API
changes in 1.4 to guide you in porting your packages:

Do also note that the Linux distros may also have a patch for their
corresponding package, in which case you can add that to your PATCH_URI.
