Updated graphics/png to 1.6.1 [kim 2013-04-01]

Version 1.6.1beta06 [March 4, 2013]
  Better documentation of unknown handling API interactions.
  Corrected Android builds and corrected libpng.vers with symbol
    prefixing This adds an API to set optimization options externally,
    providing an alternative and general solution for the non-portable
    run-time tests used by the ARM Neon code.  It also makes those tests
    compile and link on Android.
  The order of settings vs options in pnglibconf.h is reversed to allow
    settings to depend on options and options can now set (or override) the
    defaults for settings.

Version 1.6.1beta07 [March 7, 2013]
  Corrected simplified API default gamma for color-mapped output, added
    a flag to change default. In 1.6.0 when the simplified API was used
    to produce color-mapped output from an input image with no gamma
    information the gamma assumed for the input could be different from
    that assumed for non-color-mapped output.  In particular 16-bit depth
    input files were assumed to be sRGB encoded, whereas in the 'direct'
    case they were assumed to have linear data.  This was an error.  The
    fix makes the simplified API treat all input files the same way and
    adds a new flag to the png_image::flags member to allow the
    application/user to specify that 16-bit files contain sRGB data
    rather than the default linear.
  Fixed bugs in the pngpixel and makepng test programs.

Version 1.6.1beta08 [March 7, 2013]
  Fixed CMakelists.txt to allow building a single variant of the library
    (Claudio Bley):
  Introduced a PNG_LIB_TARGETS variable that lists all activated library
    targets.  It is an error if this variable ends up empty, ie. you have
    to build at least one library variant.
  Made the *_COPY targets only depend on library targets actually being build.
  Use PNG_LIB_TARGETS to unify a code path.
  Changed the CREATE_SYMLINK macro to expect the full path to a file as the
    first argument. When symlinking the filename component of that path is
    determined and used as the link target.
  Use copy_if_different in the CREATE_SYMLINK macro.

Version 1.6.1beta09 [March 13, 2013]
  Eliminated two warnings from the Intel C compiler. The warnings are
    technically valid, although a reasonable treatment of division would
    show it to be incorrect.

Version 1.6.1rc01 [March 21, 2013]
  No changes.

Version 1.6.1 [March 28, 2013]
  No changes.
Revert. It doesn't require Tk to be functional.
Changes 1.3.0:
* support for progressive jpegs added (fixes long standing "bug" of progressive jpegs becoming non-progressive during optimization),
* new options --all-normal & --all-progressive for converting jpegs to non-progressive & progressive,
* new -S / --size option to set target size for output file (enables lossy optimization),
Changes 3.7.16.1:
* Fix for a bug in the ORDER BY optimizer that was introduced in version 3.7.15 which would sometimes optimize out the sorting step when in fact the sort was required. Ticket a179fe7465
* Fix a long-standing bug in the CAST expression that would recognize UTF16 characters as digits even if their most-significant-byte was not zero. Ticket 689137afb6da41.
* Fix a bug in the NEAR operator of FTS3 when applied to subfields. Ticket 38b1ae018f.
* Fix a long-standing bug in the storage engine that would (very rarely) cause a spurious report of an SQLITE_CORRUPT error but which was otherwise harmless. Ticket 6bfb98dfc0c.
* The SQLITE_OMIT_MERGE_SORT option has been removed. The merge sorter is now a required component of SQLite.
* Fixed lots of spelling errors in the source-code comments
Fix two typos.
Changes 1.2.13:
* Drop BSD/OS and Windows 95 support.
* Rewrite most of the buildsystem, and simplify it
* System dependant code cleanup
* Move to git and rewrite of the history to get proper authorship
* Drop LaTeX documentation
* Fix build on various systems
* Fix compilation on MSVC
Changes 0.4.2:
New Features:
* Added new command line option -p, --progress: Print progress report
  while copying from the DVD; thanks to flipflip for the patch.
* Added new translations from Launchpad: Danish (da),
  English (United Kingdom) (en_GB), Estonian (et), Portuguese (pt),
  Slovak (sk), Turkish (tr)
* New complete translation: English (United Kingdom) (en_GB),
  French (fr), Italian (it), Slovak (sk)

Changes:
* Convert DVD title to lower case, but let every word in the title start
  with an upper case letter and replace underscores with spaces.

Bug fixes:
* Print the correct vob file name in which the read error happens.
* Fix DVD title detection on FreeBSD.
* Fix copying of fragmented chapters.
Updated graphics/jpegoptim; databases/sqlite3; multimedia/libdvdcss; multimedia/dvdbackup
Changes 1.5.1:
The biggest fix is for a memory leak introduced in Django 1.5. Under certain circumstances, repeated iteration over querysets could leak memory - sometimes quite a bit of it. If you'd like more information, the details are in our ticket tracker (and in a related issue in Python itself).

If you've noticed memory problems under Django 1.5, upgrading to 1.5.1 should fix those issues.

Django 1.5.1 also includes a couple smaller fixes:
* Module-level warnings emitted during tests are no longer silently hidden.
* Prevented filtering on password hashes in the user admin.
