STY: Change ITK_OVERRIDE for override in whole code (find Modules -type f -exec sed -i 's/ITK_OVERRIDE/override/g' {} +)

        clang-tidy tool can insert missing override keyword as a macro so that missing [optional] virtual identifiers can be easily added.

        build otb with clang 3.8 and use cmake option CMAKE_EXPORT_COMPILE_COMMANDS=ON. Most modules and third parties have been activated.

        #Run clang modernize check using utility script which allow to process the code in parallel (only on Applications directory)
        python run-clang-tidy.py -clang-tidy-binary ~/software/clang+llvm-3.8.0-x86_64-linux-gnu-ubuntu-14.04/bin/clang-tidy -checks=-*,modernize-use-override -header-filter=/home/grizonnetm/projets/otb/src/OTB/Modules/Modules/Applications/.*/include/.* -j8 -fix -p ~/projets/otb/bin/release/OTB-clang3.8/ ~/projets/otb/src/OTB/Modules/Applications/*/app/*.cxx  > ~/temporary/run-clang-tidy-app-log.txt

        #Replace override by ITK macro (to maintain compat with c++98) in Modules/Applications
        find . -type f -print -name "*.cxx" |xargs perl -pi -e 's/\ override/\ ITK_OVERRIDE/g'

ENH: Using the new, faster filter for zooming xs image in phr mode (in applications Superimpose and BundleToPerfectSensor)

BUG: Ensure that the Superimpose and BundleToPerfectSensor app reports the correcte geometry information (mantis #1153)

This is a big one without much harm. It fixes incorrect spelling
and grammer when packaging OTB 5.0.0 and 5.2.0 for Debian.
Most of these changes are done by developers at DebianGIS.
For more info, I include the original patch header below.
Description: Fix some spelling errors to silence lintian
enabling  to concentrate on the real problem.

BUG: Allowing to force default mode with Pleiades images in BundleToPerfectSensor and SuperImpose applications

modifications generated via the script FindRedundantHeaderIncludes.py

ENH: remove warning when phr mode is activated by the application and extend long description to describe app modes

BUG: Fixing #951 (applications does not work properly with external ITK) by replacing the ITK filter by an OTB one (which derives from our patched itk::UnaryFunctorImageFilter)

Change the shift apply in X and Y direction from 3/2 pixels to -3/2 pixels in
bundletoperfectsensor application for phr data. This
patch was provided by Julien Michel as he oberves that it improves the
fusion on PHR data.
I confirm that inverting this offset improve the result on PRIMARY product
samples over Melbourne.

It is still not clear for me if we've got now the "right" formula.
