We need new icons for org.mitk.gui.qt.segmentations.
As discussed in a couple of MITK meetings, icons should follow the Tango Icon Theme Guideline http://tango.freedesktop.org/Tango_Icon_Theme_Guidelines
The ArtLibreSet (GPL license) looks very promising / exactly what we could use: http://tango.freedesktop.org/ArtLibreSet
Please check the implications of the GPL license for the usage of unmodified icons in BSD licensed and proprietary software modules. A friendly mail to the tango-artists mailing list could help to clarify this issue. We could also just ask if they allow us to use these icons for org.mitk.gui.qt.segmentation and all tools included in this bundle (for ExtApp and 3M).
