MITK should migrate to use the ITK 5.x series. This task is meant to document findings, overall progress etc..
Official migration guide is here: https://github.com/InsightSoftwareConsortium/ITK/blob/master/Documentation/ITK5MigrationGuide.md
- After migration, we should go through all filters that implement ThreadedGenerateData(), to check, if they have a constructor that calls this->DynamicMultiThreadingOff();. Otherwise they should override DynamicThreadedGenerateData() instead.
