With T3632 MITK's DisplayGeometries are able to restrict zooming and panning. This behavior can be turned on or off by the user of DisplayGeometry. The default is "no restrictions" to imitate behavior of old MITK applications.

Should we change the default to "restrict zooming/panning"?

The change could be implemented by toggling the constructor initialization of m_ConstrainZoomingAndPanning in line 397 of mitkDisplayGeometry.cpp.

I don't see any reason to favor the old MITK behavior. Should be discussed shortly in the MITK meeting, however.
