latest version of libpng

[Riccardo Mottola]

Hi,

I'm confused about our libpng versions!

/opt/csw/lib/libpng.so -> libpng15.so
lrwxrwxrwx   1 root     root          16 Sep 18  2012 
/opt/csw/lib/libpng.so.3 -> libpng.so.3.50.0

lrwxrwxrwx   1 root     root          18 Sep 18  2012 
/opt/csw/lib/libpng12.so.0 -> libpng12.so.0.50.0
-rwxr-xr-x   1 root     bin       200752 Sep 18  2012

lrwxrwxrwx   1 root     root          19 Nov 11  2012 
/opt/csw/lib/libpng15.so.15 -> libpng15.so.15.13.0
-rwxr-xr-x   1 root     bin       234128 Nov 10  2012 
/opt/csw/lib/libpng15.so.15.13.0


we have versoned names for 12 and 15 but what is libpng.so.3 which would 
look as the correct one? I see the series a 1.0, 1.2, 1.5...

On my own box I and up having libpng3.. Just to know about this oddity.

There are some security updates, I'll try my best updating libpng, but 
wanted to now this oddity first.
