  attribute for each part.
* iconvert: properly handle multi-image files for formats that can't
  append subimages.

* Strutil::split() fixes bug when maxsplit is not the default value.
* Fix ImageCache::get_pixels() for the chbegin != 0 case, when cache
  and output buffer types were not identical.
* DPX bug fix -- inappropriate use of "dpx_ImageDescriptor" could make
  invalid DPX files (especially when reading metadata from one DPX
  file, changing the number of channels, then writing out again as a
  DPX file).

Release 1.3 (2 Dec 2013 -- compared to 1.2.x)
----------------------------------------------
Major new features and improvements:
* Huge overhaul of the Python bindings: TypeDesc, ImageSpec (1.3.2),
  ImageInput, ImageOutput (1.3.3), ROI, ImageBuf (1.3.4), ImageBufAlgo
  (1.3.6).  The Python bindings were pretty rusty, badly tested,
  undocumented, and had not kept up with recent changes in the C++ APIs.
  That's all fixed now, the Python APIs are finally first-class citizens
  (including full functionality, unit tests, and docs), and we intend to
  keep it that way.
* The ability for an application to supply custom ImageInput and associate
  them with a file extension. Those II's can do anything, including
  generate image data procedurally.
* GIF reader

Public API changes:
* Large overhaul of the Python bindings. See the (finally existing!) docs.
* ImageBufAlgo:
  * New functions: nonzero_region(); ociodisplay(), resize() variety
    that lets you specify the filter by name; 2-argument (non-in-place)
    versions of add, sub, mul, rangecompress, rangeexpand, unpremult,
    premult, clamp fixNonFinite; sub() varieties that take float or
    float* operands.
  * Removed several IBA functions that have been deprecated since 1.2.
  * Deprecated the single-image in-place versions of add, sub, mul,
    rangecompress, rangeexpand, unpremult, premult, clamp fixNonFinite.
* ImageBuf:
  * read() and init_spec() are no longer required, somewhat simplifying
    application code that uses ImageBuf.  All ImageBuf API calls
    automatically read the spec and/or pixels from their named file if
    they are needed, if it has not already been done.  (1.3.4)
  * save() is deprecated, and new ImageBuf::write() is now preferred
    (naming symmetry). (1.3.4)
  * New set_write_format() and IB::set_write_tiles() allow override of
    default choices for data format and tile size for subsequent calls
    to ImageBuf::write(). (1.3.4)
* ImageCache / TextureSystem:
  * ImageCache::add_file() lets you seed the ImageCache with a "virtual \ 
file"
    that will read from a custom ImageInput.  This lets you add "procedural
    images" to the IC.
  * ImageCache::add_tile() lets you add tiles to the ImageCache. The caller
    can initialize those tiles with any pixel values it chooses.
  * A new variety of IC/TS::destroy() takes a 'bool teardown' parameter
    that, when true, does a complete teardown of the underlying ImageCache,
    even if it's the "shared" one. (1.3.7)
* OIIO::declare_imageio_format() exposes a way to give OIIO a custom
  ImageInput and/or ImageOutput (via factory functions) and associate them
  with particular file extensions. This makes it especially easy for an
  app to make a procedural image generator that looks to the entire rest
  of OIIO like a regular image file. (1.3.2)
* TypeDesc::VECSEMANTICS now have additional enum tags for TIMECODE and
  KEYCODE to indicate that the data represents an SMPTE timecode or
  SMPTE keycode, respectively. (1.3.7)

Fixes, minor enhancements, and performance improvements:
* oiiotool improvements:
  * --autotrim   Shrinks pixel data window upon output to trim black
    edges. (1.3.2)
  * --siappend   Appends subimages of top two images on the stack. (1.2.2)
  * --datadump will print all pixel values of an image (debugging tool) (1.3.6)
  * --flatten turns a "deep" image into a flat one by \ 
depth-compositing within
    each pixel (1.3.6).
  * --ociodisplay  applies an OpenColorIO display transformation. (1.3.7)
  * Fix memory leak when processing frame range. (1.2.1/1.3.2)
  * --help now returns a success error code, not a failure. (1.2.1/1.3.2)
  * Fix incorrect help message about --ociolook. (1.2.1/1.3.2)
  * Fix typo in "oiio:Colorspace" attribute name that interfered
    with correct color space conversion in --colorconvert. (1.2.1)
  * Many fixes and improvements to XMP & IPTC metadata handling. (1.2.2)
  * Multithread speed improvement when opening files by reducing how
    much time ImageInput::create and/or ImageOutput::create hold a
    global mutex.
  * oiiotool --origin and --fullpixels, when operating on cropped or
    overscanned image, could sometimes do the wrong thing. (1.2.2/1.3.3)
  * oiiotool --colorconvert did not work properly when the color
    transformation was detected to be a no-op. (1.2.2/1.3.3)
  * oiiotool --fit did not handle padding or offsets properly. (1.2.2/1.3.3)
  * Changed/improved the behavior of --rangecompress/--rangeexpand. (1.3.3)
  * 'oiiotool --pattern checker' was incorrect when nonzero offsets were
    used. (1.2.3/1.3.4)
  * oiiotool --runstats prints the total time/memory on every iteration
    when doing file sequence wildcard iteration. (1.3.4)
  * Eliminated a particular situation that might hit an ASSERT. Instead,
    bubble up a real error message. (1.3.4)
  * oiiotool --resize and --resample fixed for overscan images (1.3.5)
  * --ociolook applies OCIO looks. (1.3.6)
  * Supports printf-style frame range wildcards ('%04d') in addition to the
    '#' style, and scan for matching frames if no explicit framespec is
    provided. (1.3.6)
* ImageBufAlgo improvements:
  * colorconvert() did not work properly when the color transformation was
    detected to be a no-op.
  * colorconvert(): added a variety that specifies color spaces by name.
  * New ociolook() function applies OCIO "looks." (1.3.6)
  * checker() was incorrect when nonzero offsets were used.
  * checker() now has default values of 0 for the 'offset' parameters
    (and so may be omitted if you want 0 offsets). (1.3.4)
  * unsharp_mask() bug when src and dst were different data formats.
    (1.2.3/1.3.4)
  * Better dealing with cases of IBA functions detecting and issuing
    errors when inputs that must be initialized are not. (1.3.4)
  * We changed the behavior of rangecompress/rangeexpand.  We swear
    the new way is better. (1.3.3)
  * New nonzero_region() returns the shrink-wrapped nonzero pixel data window.
    (1.3.2)
  * resize() has a new variety that lets you specify the filter by name
    (rather than allocating ans passing a Filter2D*).
  * resize() and resample() fixed to more robustly handle overscan
    images. (1.3.5)
  * over()/zover() are no longer restricted to float images. (1.3.7)
* ImageBuf:
  * ImageBuf::write() writes untiled images by default, fixing some
    tricky issues when IB's start thinking they're tiled because of
    interaction with the ImageCache (which makes everything look tiled).
  * ImageBuf::file_format_name() never worked properly, now is fixed (1.3.4)
  * Fixed bug that caused incorrect ImageBuf::copy_pixels() when the two
    IB's had different data types.  (1.3.4/1.2.3)
  * Improved iterator's handling of how overscanned pixels interact
    with wrap modes. (1.3.6)
  * Fixed a bug with black wrap mode not working correctly. (1.3.7/1.2.4)
* ImageCache/TextureSystem:
  * More careful with texture de-duplication -- texture value lookups
    use de-duplication, but metadata lookups (e.g., get_texture_info)
    uses the metadata from the original file.
  * get_image_info/get_texture_info queries for "datawindow" and
    "displaywindow". (1.3.6)
  * The multi-point version of environment() was broken. (1.3.9)
* maketx: --hicomp uses the new range compression/expansion formula.  (1.3.3)
* DPX:
  * support multi-image (often used for stereo frames).
  * Fixed DPX input that didn't recognized offset/cropped images.
    (1.2.2/1.3.3, another fix in 1.3.4)
  * Fixed DPX output crash with cropped images. (1.2.2/1.3.3)
  * Now correctly get and set "smpte:TimeCode" and \ 
"smpte:KeyCode"
    metadata.  (1.3.7).
* OpenEXR:
  * Fixed write_scanlines handling of per-channel data types (1.3.6)
  * Several OpenEXR 2.0 deep file fixes: only some compression types
    supported, write_tiles passed wrong parameters, must suppress some
    attribute names. (1.2.3/1.3.6)
  * Now correctly get and set "smpte:TimeCode" and \ 
"smpte:KeyCode"
    metadata.  (1.3.7).
* JPEG: fixed that some JPEG files were not being recognized because of
  magic number issues.
* TGA: Correctly unassociate alpha if it's from an unasociated file;
  also, always write unassociated data because so few Targa readers in
  the wild seem to properly handle associated alpha.
* PNG: More correct handling of unassociated alpha.
* TIFF: More correct handling of unassociated alpha.
* PSD: fix handling of associated vs unassociated alpha. (1.2.3)
* maketx fixed to handle inputs that are a mixture of cropped and
  overscanned. (1.3.5)
* Fix segfault if OCIO is set to a non-existant file. (1.3.6)
* Slight performance increase when writing images to disk (1.3.6)
* Many fixes to make OIIO compile with libc++ (clang's new C++ library,
  and the default on OSX Mavericks). (1.2.3/1.3.6, 1.3.7)
* Fixed several potential buffer overflow errors from unsafe strcpy. (1.3.8)

Build/test system improvements:
* Fix broken tests under Windows. (1.3.2)
* Many fixes for compiler warnings on various platforms: fmath_test.cpp,
  field3dinput.cpp, sysutil.cpp, argparse.cpp, oiiotool.cpp. (1.2.1/1.3.2)
* Fixes problems on little-endian architecture with texture3d.cpp.
  (1.2.1/1.3.2)
* Fix compilation problems on architectures with gcc, but no 'pause'
  instruction. (1.2.1/1.3.2)
* Fix build search path for correctly finding libopenjpeg 1.5. (1.2.1)
* Work around bug in older MSVC versions wherein Filesystem::open needed
  to explicitly seek to the beginning of a file. (1.2.1/1.3.2)
* Build fixes for FreeBSD. (1.2.1/1.3.2, 1.2.4/1.3.6)
* Fix testsuite/oiiotool on Windows -- windows shell doesn't expand
  wildcards. (1.2.1/1.3.2)
* Fix warnings for new GCC 4.8 compiler.
* Always search for and use the release HDF5 libraries, not the debugging
  ones, even when building debug OIIO (this fixes errors when a system
  does not have the debugging HDF5 libraries installed). (1.2.2/1.3.3)
* Extensive unit tests in the testsuite for the Python bindings.
* Fix compiler error on MIPS platform. (1.2.2/1.3.3)
* Add FIELD3D_HOME description to 'make help' (1.2.2/1.3.3)
* Add cmake variables ILMBASE_CUSTOM_INCLUDE_DIR, ILMBASE_CUSTOM_LIB_DIR,
  OPENEXR_CUSTOM_INCLUDE_DIR, and OPENEXR_CUSTOM_LIB_DIR to make it
  easier to have site-specific hints for these packages' locations. (1.3.4)
* Add BOOST_HOME and OCIO_HOME controls from the top-level Makefile wrapper.
  (1.3.4/1.2.3)
* Accommodate new cmake release that slightly changes the HDF5 library
  naming. (1.3.6)
* Various fixes to make the code compile properly with libc++ (clang's
  rewrite of the C++ standard library). (1.3.6)
* Updated PugiXML (partly to help compilation with libc++) (1.3.6)
* Better support for NOTHREADS (for some legacy systems) (1.3.6)
* Fix to __attribute__(visibility) for gcc < 4.1.2 (1.3.6)
* Improve the CMake build files to fully quote path constructions to make
  it more robust for builds with paths containing spaces. (1.3.7)
* Moved the main CMakeLists.txt file to the top level directory, per usual
  CMake conventions. (1.3.7)

Developer goodies:
* Docs improvement: full documentation of ImageBufAlgo. (1.2.1/1.3.2)
* Merge improved "Tinyformat" that fixes a bug in some old glibc versions
  (1.3.2).
* Now each command line tools explicitly converts to UTF native arguments,
  rather than relying on it happening in ArgParse (which no longer does
  so). (1.3.2)
* Strutil::contains() and icontains(). (1.2.2/1.3.3)
* Updatd "Tinyformat" to the latest release (1.3.6)
* Sysutil::physical_memory() tries to figure out the total physical memory
  on the machine. (1.3.6)
