Added new test to reproduce bug #1926, i.e., reconstructed fov smaller than max possible
Fix for bug #1926: since the projection size might change from pass to pass in GenerateData, it is better to allocate memory at each projection
Fixed bug at corner of image: do the same as when there is no intersection
Request for largest possible region of projections if the camera is in
the requested region of the volume
Removed main direction box change which was causing a discontinuity in the projection images
Adapted test to previous correction, we now remove half a pixel in every direction
Made Cuda forward projector consistent with Joseph's
Merge branch 'master' of github.com:SimonRit/RTK
Fixed bug: projection stack was not adequately covered when trying to
calculate the requested region
Added a half voxel border around volume to test if camera is in
Looking for the source position was not the right fix, look for sign change in perspective
flip Shroud signal output

Flip shroud signal now the maximum correspond to end-exhale and the
minimum to end-inhale phase which seems more natural.
Change amsterdam shroud test to pass
Option to add gaussian noise
Merge branch 'master' of github.com:SimonRit/RTK
Added test to reproduce bug #1939
Removed unused stuff from rtkConfiguration.h and added ITK4 compatibility definess
Added test without fftw
Make sure that FFTW is not used with ITK4 as well
Fixed two problems:
- ITK4 compatibility: was not using the correct filter
- requested region should be enlarged to largest along y when a Hann windowing is requested in that direction
