- 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.

Changes since the last public release (1.6.22):
Stop a potential memory leak in png_set_tRNS() (Bug report by Ted Ying).
Fixed the progressive reader to handle empty first IDAT chunk properly
(patch by Timothy Nikkel). This bug was introduced in libpng-1.6.0 and
only affected the libpng16 branch.
Added tests in pngvalid.c to check zero-length IDAT chunks in various
positions. Fixed the sequential reader to handle these more robustly
(John Bowler).
Corrected progressive read input buffer in pngvalid.c. The previous version
the code invariably passed just one byte at a time to libpng. The intent
was to pass a random number of bytes in the range 0..511.
Moved sse2 prototype from pngpriv.h to contrib/intel/intel_sse.patch.
Added missing ")" in pngerror.c (Matt Sarrett).
Fixed undefined behavior in png_push_save_buffer(). Do not call
memcpy() with a null source, even if count is zero (Leon Scroggins III).
Fixed bad link to RFC2083 in png.5 (Nikola Forro).
Changes since the previous public release (version 1.6.36)
