3D Paintbrush:  enabled the drawing with the Radius=0

FireVoxel Build 206A is released.

Use Interface options dialog:  removed the "Synchronized cursor" option.

Dynamic Modelling:  Input Function correlation model:  fixed the bug and checked the correctness on the identity problem.

FireVoxel Build 206 is released:

1. IVIM free model fix:  was always returning "0" as the residual of the fit.
2. ABT test for Dynamic Modelling:  modified the test so that results are compared to Standard using the specified tolerance (1e-3) to avoid costly investigation into ABT trivial "red flags".
3. Mouse brain  PET-CT-Atlas workflow:  verified that workflow works with the complete 20-region atlas.
4.Produced a Mouse brain atlas of all 20 regions that can be now processed by the Layer Control dialog.
5. Expanded current Layer Control dialog to 22 layers to accommodate an entire Mouse Brain Atlas.
6. Fixed the .IM Save\Load problem
7. Implemented a very early prototype of the new Layer Control dialog box.  This Control would provide handling of all hybrid types of the primitives present in the FireVoxel entity:  {Volumes,Landmarks,VROIs,Pollygons,Text, etc}.  This dialog supports an unlimited number of layers. During the prototyping stage this dialog is activated by F9.
8. Code improvement:  moved the CDlgLayerCtrl declaration within the class source module.
9 Dynamic Modelling module:  implemented the Parametric map "Input function correlation"
10. Femur ROI registratio: Implemented a dedicated menu item with parameters suitable for this application.
11. ROI->ROI registration: Developed the Signal difference calculation working directly with Run-length representation of ROIs (x10-20 memory compact) that resulted in x10 speed up during the AutoFocus on Subscale=3. Speed up is even higher on the Finetune phase approaching

Visual Correlation (?) comparison between supplied AIF and 1-voxel ROI

note: the signal baseline in this particular dialog = 186
