Fixed misinterpretation of dtex samples in deepopacity case, updated README, comments, and ChangeLog to reflect fix.
Namespace clean up
Pass at fully qualifying FLOAT, UINT to avoid build issues.
follow up to previous checkin on fully qualified FLOAT
Added a missing file to CMakelist file.
Adding linux debug trap code.
Merge branch 'cmake-fixes' into develop
missing system include
Merge branch 'develop' of https://github.com/openexr/openexr into develop
This commit fixes several problems with DtexToEXR.

1: The files were flipped upside down. This is fixed.

2: The files were transposed rather than rotated with the --sideways flag, which has now
been fixed as well.

3: The data window was the wrong size, this has been fixed.

4: The default options are now are true for deep rgb, and the command line usage has been changed to
reflect these new defaults.
Fixed include paths.

Pass _data->header to writeMagicNumberandVersionField()

Making this change in the OStream version of the constructor so that it
matches the const char * version. Otherwise we get a bug where files
made with an OStream won't get their version flags set properly.
A quick fix for dealing with deep data in exrdisplay.
This introduces a -noDeepComp / -d flag that simply presents the first sample in the samples list.
We also do a manual implementation of the deep comp for the tiled deep images.
@TODO implement the deep comp for the DeepTiled code.
Added a namespace alias file to make the code less verbose.
Formatting clean-up
Merge branch 'item72' into develop
sync up with internal ILM code

Some (future?) python interpreters want __truediv__ instead of __div__.
In some instances the '/' operator was not found.
Looks like the python interpreter wants __truediv__
and/or __itruediv__ instead of the original __div__ or __idiv__.
Added these new operator bindings to all PyImath variables that currently
have __div__ or __idiv__ bindings.  Refer to this link for more information on __truediv__.

Thread some QuatArray methods
        For performance reasons (and consistency) these methods
        have been threaded in PyImath.  We also add a new convinience
        method on to the QuatfArray and QuatdArray data structures
        called 'orientToVectors'.  Before in some scripts I would
        call:
                    orient = imath.QuatfArray(l)
             euler = imath.orientToVectors(forward, up, alignForward)
                    orient.setEulerXYZ(euler)
        but now we can just call:
             orient = imath.QuatfArray(l)
                     orient.orientToVectors (forward, up, alignForward)
        so this saves a step and some memory (and probably a little
        better performance).  In my tests so far, the results are
        exactly the same as before (as they should be).
