The bundle org.mitk.gui.qt.regiongrowing does not work properly anymore. It will be used for an MITK tutorial and should:
- display seed points ABOVE any pictures
- use DataManagers selection events
- "Seedpoints" should be "seed points"? (should be checked)
- loading/saving should be tested
- Qt layout looks a bit broken on MacOS (at least), margin too big around the four buttons
- the code should look clean and easy
