Build 458 is released.

 1. When parsing the DICOM tree: we determine if the files were deidentified and in that case we add the PatientID to distinguish between different patient's records.

2. Corrected defect:  New layer addition and paintbrush usage now set the DocumentModified flag. So there is a warning when the User tries to close the document.

3. FLEXR3D processing dialog: added an option to save FFF (flow field file).

4. MainMenu>Tranform:  added an option to transform using FFF file.

5.  FLEXR3D\FLEXRMC added warning when SSC measure is selected to ensure the feature keypoints are enabled.

6.  Added UI Function>Test :  Combine Probability Maps to Atlas.

7.   Added UI Function>Test :  Sharpen template using Atlas

8. FLEXR cross-correlation similarity measure:  on large appertures (~16vox) obtained a 20% speed up by re-arranging the memory access during parallel execution.

9.  FLEXR SSC measure calculation : removed a major memory leak.

10. Further optimization of Crosscorrelation measure (FLEXR):  using the x86 superscalar instructions and 32-bit floating precision, achieve 32 threads X 16 superscalar operations = x512  parallelization.

11. Removed NGF (Normalize Gradient Field) similarity measure from FLEXR3D\FLEXRMC dialog options.

12. Enable the SSC similarity measure in FLEXR-MC dialog box.

13. Model 17 (IVIM segmented fit):  substantial update with improved parameter ranges etc.

14. Model 18 (IVIM biexp fit): provided update for the ranges of fitted parameters.

15. Parametric modelling dialog: when model changes - the Output parameters selection gets all unchecked to avoid confusion.

16. Corrected behavior when the new layer is added and it has diferent spatial attributes.  Now it ensures that everything matches to the base layer (resolution, slice position, orientation, etc).

17. Merged PWR.DLL and VolumeAnalyze.dll (VolumeAnalyze is removed from distribution now). This is done for linkage efficiency and removing redundancies.
