v1.2.2

* tag 'v1.2.2': (101 commits)
  set version to v1.2.2 in case we want to release with recent bugfix without deleting v1.2.1 release tag
  fix backwards test of all columns mode in erosion
  Changed workbench version to 1.2.1 for release that contains functionality for Nature paper.
  Added the border offset to scenes and disallow a negative offset.
  continuing last commit, allow negative offset.
  Added offset OpenGL polygon offset for borders.  BUT, is does not offset borders because borders are drawn as lines and polygon offset does not work on lines.  So, the polygon offset is applied when the surface is drawn.  This is experimental and controlled in the Features Toolbox->Border->Attributes->Above Offset.
  Units listed in border line width spin box was millimeters (mm) and has been corrected to be pixels (px).
  Implemented WB-633 New requirements for updating of connectivity data.  However, its functionality is disabled due to potential problems with the functionality for users.  Can be enabled by changing variable 'allFilesFlag' in CiftiConnectivityMatrixDataFileManager::getDisplayedConnectivityMatrixFiles().
  add a newline to -arguments-help for consistency
  A flag in Brain.cxx used during spec file reading was set, but not reset, when after reading spec file content from a scene.
  WB-626 Dynamic Correlation of Dense Time Series Without Computation of Dense Connectome: The dense dynamic file (encapsulated in a data-series file) is now lazily initialized.  This prevents its initialization (and loading of data) when file information is run with an option that inhibits loading of data such as "-no-map-info".
  comment out timing info from data series, was breaking scripts
  make NiftiIO tolerate attempted multithreaded access (CaretBinaryFile's interface has separate seek and read/write functions, so a mutex there wouldn't achieve much)
  quick fix for crashing with -file-information -no-map-info on dtseries (was trying to read cifti rows in parallel from disk, which is not yet reentrant)
  Add use of OpenMP to dense dynamic file and timing to load data for a surface node.
  Added timing around initialization of dense dynamic file
  Resolve WB-631 voxel selection in oblique volume viewing does not go to correct slice: When in an oblique view, allow all of the slice indices to change.  This problem was probably caused long ago by a modifictation that prevented the slice index related to the viewed axis from changing in volume slice montage.
  Resolve WB-629 Volume crosshairs don't intersect surface contour in oblique view: When drawing crosshairs, unique translations were needed for each slice view plane (axial, coronal, parasagittal).
  WB-628 Ability to adjust NIFTI sform dynamically in wb_view: Added ability to adjust the 'depth' of an image displayed in wb_view.
  Resolve WB-630 wb_view may crash if tile tabs enabled with fewer cells than tabs: Limit number of tabs drawn to the number of cells.
