The 2D FiberMapper seems to be much slower than previously.
Maybe reasons include:
- it produces a lot of update-messages in the command line:
"core.mod.difImg.fiberbundlexMap2d: MapperFBX 2D update:"
- when starting tractography with concurrent visualization, many vtk-errors pop up:
"ERROR: In ..\..\VTK-src\Rendering\vtkGLSLShader.cxx, line 359
vtkGLSLShader (000000002210E4C0): Found unchecked OpenGL error."
