FireVoxel  283A is released.

1.  Added the DisplayTransform record to the ZOOMCACHE structure.  This fixes some defects when switching between Film and Slice view and pulling the Zoom from cache.

2.  When new layer is added\created, immediately copy the Display Matrix of the current working layer.  This way the drawing can be done correctly on the newly created layer.

FireVoxel Build 282 is released.

Dynamic modelling,  models  #{43,46,47}

1.  Added a hypermarameter:  "Minimal Arterial Delay"
2. When iterating through the Arterial Delay values using the Arterial Delay Delta ensured that
the Max Arterial Delay value is always evaluated for any Delta.

Build 280 is released.

1.  Implemented "Arterial Delay" parameter for Model #43 2CXM.  Fitting residuals can be dropped by half on the test images.







2.  Changed default processing when loading DICOM images with IPP\IOP tags missing.  This allowed to load some volumes as 3D as desired.

3. Implemented new dynamic model "2CFM {vp,ve,Fp,PS} - Gridded Simplex Local Optimization".  This implementation contains the Arterial Delay output parameter.

4.  Fixed defect : when new ROI layer is created from Layer Control dialog box, the ROI slice dicom image position and orientation were not properly initialized.  This resulted in defect when loading the ROI volumes saved as 3D DICOM.

FireVoxel Build 279 is released.

1.  Combine and synchronized the Volume viewing pipeline (3D->Screen  affine transform) with the transform used to convert paintbrush screen coordinates into the voxel coordinates.  This fixed the defects with drawing ROI on various projections.
