- Updates libpng to 1.6.37 (from 1.6.23) 
Note: Seems svn can't merge it automatic when a folder was removed and readded with same name. 
Easier to update libs by deleting all files - copying new ones over and then check svn stat for differences
and resolve them manually.

.SH NAME
png \- Portable Network Graphics (PNG) format
.SH DESCRIPTION
PNG (Portable Network Graphics) is an extensible file format for the
lossless, portable, well-compressed storage of raster images. PNG provides
a patent-free replacement for GIF and can also replace many
lossless, portable, well-compressed storage of raster images. PNG
provides a patent-free replacement for GIF, and can also replace many
common uses of TIFF. Indexed-color, grayscale, and truecolor images are
supported, plus an optional alpha channel. Sample depths range from
supported, plus an optional alpha channel. Sample depths range from
1 to 16 bits.

PNG is designed to work well in online viewing applications, such as the
World Wide Web, so it is fully streamable with a progressive display
option. PNG is robust, providing both full file integrity checking and
fast, simple detection of common transmission errors. Also, PNG can store
gamma and chromaticity data for improved color matching on heterogeneous
platforms.
