Added OpenEXR library v1.7.1

3rdparty/ilmimf/README

-ABOUT THE OPENEXR LIBRARIES
-----------------------------
-
-Half is a class that encapsulates our 16-bit floating-point format.
-
-IlmThread is a thread abstraction library for use with IlmImf.  It
-currently supports pthreads and Windows threads.
-
-IlmImf is our "EXR" file format for storing 16-bit FP images.
-
-Imath is a math library.  IlmImf only uses a subset of it,
-but we're releasing the full library because it's easier for us to 
-maintain, and we think it'll be useful to others.
-
-Iex is an exception-handling library.
-
-See the IlmImfExamples directory for some code that demonstrates how
-to use the IlmImf library to read and write OpenEXR files.  The doc
-directory contains some high-level documentation and history about the
-OpenEXR format.
-
-If you have questions about using the OpenEXR libraries, you may want
-to join our developer mailing list.  See http://www.openexr.com for
-details.
-
-
-LICENSE
--------
-
-The OpenEXR source code distribution is free software.  See the file
-named COPYING (included in this distribution) for details.
-
-
-WHAT'S INCLUDED
----------------
-
-Besides the core OpenEXR libraries, the release includes several 
-utilities for reading, writing, viewing, and manipulating OpenEXR 
-images.  These include:
-
-  * exrdisplay, an image viewer.
-  * exrheader, a utility for dumping header information.
-  * exrstdattr, a utility for modifying OpenEXR standard attributes.
-  * exrmaketiled, for generating tiled and rip/mipmapped images.
-  * exrenvmap, for creating OpenEXR environment maps.
-  * exrmakepreview, for creating preview images for OpenEXR files.
-
-exrdisplay requires FLTK 1.1 or greater and OpenGL.  exrdisplay
-supports fragment shaders if you have the Nvidia Cg SDK and a graphics
-card capable of running fp30 profile fragment shaders.  See
-exrdisplay/README for details.
-
-We have also released an OpenEXR display driver for Renderman, a file
-I/O plugin for Shake, and a file I/O plugin for Adobe Photoshop (on
-both Windows and MacOS).  These are packaged separately.  Go to
-http://www.openexr.com to download them.  NOTE: the most recent
-versions of these applications now have native support for OpenEXR, so
-you should only use our open-source versions of the plugins if you
-have an older version of the application.
-
-
-BUILDING OPENEXR
-----------------
-
-Building OpenEXR requires the zlib library.  If you want to build the
-'exrdisplay' image viewer, you'll also need FLTK 1.1, but this program
-is not required to use OpenEXR's libraries in your application.
-exrdisplay can also accelerate the display of OpenEXR images if you
-have the NVIDIA Cg SDK.
-
-Your OS distribution may already include these libraries, or supply
-packages for them.  That is the preferred way to obtain them for use
-with OpenEXR.  If not, you can obtain the source code for zlib and
-FLTK from:
-
-   http://www.zlib.net
-   http://www.fltk.org
-
-and you can download the NVIDIA Cg SDK from
-http://developer.nvidia.com.
-
-If you're building OpenEXR on a Windows platform, see README.win32 for
-instructions on how to build OpenEXR.  The remainder of this file
-applies only to GNU/Linux or other UNIX-like systems.
-
-After installing the required libraries, to build OpenEXR on
-GNU/Linux or other UNIX-like systems, do this:
-
-./configure
-make
-make install
-
-unless you obtained OpenEXR directly from CVS, in which case you
-should first read README.CVS.
-
-If you have the Nvidia Cg SDK and you want to build support for
-fragment shaders into exrdisplay, specify the path to the SDK using
-the "--with-cg-prefix" flag.  There are some additional compile-time
-configuration options available; type `./configure --help` for more
-information.
-
-See README.OSX for details on building OpenEXR in MacOS X.
-
-Do `make check` to run the OpenEXR confidence tests.  They should all
-pass; if you find a test that does not pass on your system, please let
-us know.
-
-Other UNIX variants haven't been tested, but should be easy to build.
-Let us know if you're having problems porting OpenEXR to a particular
-platform.
-
-All include files needed to use the OpenEXR libraries are installed in the 
-OpenEXR subdirectory of the install prefix, e.g. /usr/local/include/OpenEXR.
-
-
-USING OPENEXR IN YOUR APPLICATIONS
-----------------------------------
-
-On systems with support for pkg-config, use `pkg-config --cflags
-OpenEXR` for the C++ flags required to compile against OpenEXR
-headers; and `pkg-config --libs OpenEXR` for the linker flags required
-to link against OpenEXR libraries.

3rdparty/openexr/ChangeLog.ilmbase

+Version 1.0.3
+        * Added support for enabling/disabling large stack optimisations, used in
+          halfFunction.h.
+          (Piotr Stanczyk)
+	* Added ImathNoise.(h/cpp) files. Initializes Perlin noise to match the
+	  Renderman implmenetation.
+	  (Pixar Contribution)
+	* Fixed a number of missing includes to comply with stricter 
+	  enforcement by gnu compilers.
+	  (Piotr Stanczyk)
+	* Depracated compiler flag: -Wno-long-double since it is no longer
+	  supported under OS X.
+	  (Piotr Stanczyk)
+	* A minor API change to Imath::Frustum has been made:  the functions
+	  'near' and 'far' have been renamed to 'nearPlane' and 'farPlane' due
+	  to conflicts with certain windows headers.  The former alternate
+	  accessor names for these values on windows ('hither' and 'yon')
+	  remain, though should be considered deprecated.
+	  (David Lenihan)
+	* Added SVD, eigenvalue solver, and procrustes fit calculations
+	  to ImathMatrixAlgo.
+	  (Chris Twigg, Ji Hun Yu)
+	* Added Imath::FrustumTest for frustum visibility testing.
+	  (Eric Johnston)
+	* Fixed a stack corruption in the matrix minorOf functions.
+	  (Nick Rasmussen)
+	* Visual studio 2008 project files have been added to the vc/vc9
+	  directory, and several minor visual studio compile fixes have
+	  been applied.
+	  (Nick Rasmussen)
+	* Updated the so verison to 7.
+	  (Piotr Stanczyk)
+	* Depracated the MacCode_Warrior and Shake submodules.
+	  (Piotr Stanczyk)
+
+Version 1.0.2
+	* Added support for targetting builds on 64bit Windows and minimising 
+	  number of compiler warnings on Windows. Thanks to Ger Hobbelt for his
+	  contributions to CreateDLL.
+	  (Ji Hun Yu)
+	* Removed a spurious restrict qualifier in the matrix manipulation code
+	  that was causing the 64-bit MS compiler to generate code in release 
+	  mode that caused incorrect results. 
+	  (Ji Hun Yu)
+	* Added patches for improving universal binaries on OS X. Thanks to
+	  Paul Schneider for the contribution
+	  (Piotr Stanczyk)
+	* Imath::Box optimization: remove loops from methods by partially 
+	  specializing the class, for boxes of two and three dimensions.
+	  (Piotr Stanczyk)
+	* Added explicit copy constructors to Imath::Matrix33<T> and
+	  ImathMatrix44<T> to make conversions between float and double
+	  matrices more convenient.
+	  (Florian Kainz)
+	* Added slerpShortestArc() and euclideanInnerProduct() functions
+	  to Imath::Quat<T>.
+	  (Nick Porcino)
+	* Added 4D vector class template Imath::Vec4<T>.
+	  (Nick Porcino)
+	* Copy constructors and assignment operators for Matrix33<T>
+	  and Matrix44<T> are up to 25% faster.  Added matrix constructors
+	  that do not initialize the matrix (this is faster in cases where
+	  the initial value of the matrix is immediately overwritten anyway).
+	  (Nick Porcino)
+	* Rewrote function closestPointOnBox(point,box).  Shortened
+	  the code, improved numerical accuracy, fixed a bug where
+	  closestPointOnBox(box.center(),box) would return the center
+	  of the +Z side of the box, even if the +/-X or +/-Y sides
+	  were closer.
+	  (Florian Kainz)
+	* Rewrote function findEntryAndExitPoints() in ImathBoxAlgo.h.
+	  Results are now consistent with those from intersect(), also
+	  in ImathBoxAlgo.h.
+	  (Florian Kainz)
+	* Made Vec2<T>::length() and Vec3<T>::length() more accurate for
+	  vectors whose length is less than sqrt(limits<T>::smallest());
+	  (Florian Kainz)
+	* Made Quat<T>::angle() more accurate for small angles.
+	  (Don Hatch) 
+
+Version 1.0.1:
+	* Removed Windows .suo files from distribution.
+	  (Eric Wimmer)
+
+Version 1.0.0:
+	* Bumped DSO version number to 6.0
+	  (Florian Kainz)
+	* Rounding during float-to-half conversion now implements
+	  "round to nearest even" mode: if the original float value
+	  is exactly in the middle between the two closest half values
+	  then rounding chooses the half value whose least significant
+	  bit is zero.
+	  (Florian Kainz)
+	* Installation Tuning:
+	  - Corrected version number on dso's (libtool) - now 5.0
+	  - Separated ILMBASE_LDFLAGS and ILMBASE_LIBS so that test programs
+	    in configure scripts of packages dependent on IlmBase can link
+	    with static libraries properly
+	  - eliminated some warning messages during install
+	  (Andrew Kunz)
+	
+Version 0.9.0:
+	* Initial release of this code as a separate library.
+	  Previously the libraries contained were part of
+	  version 1.4.0 of OpenEXR
+	* New build scripts for Linux/Unix
+	  (Andrew Kunz)
+	* New Windows project files and build scripts
+	  (Kimball Thurston)

+//			  defaultValue,
+//			  posInfValue, negInfValue,

+//	evaluates the function for all finite half values in the interval

+//	For finite half values that are not in [domainMin, domainMax], the
+//	constructor stores defaultValue in the table.  For positive infinity,
