Two last corrections:
- Viewport was not written during automatic export of XML files, because Virtualization of XMLSettingsTree did not work due to inconsistent function definition (const vs. non-const)
- Some of the default parameter-file had "Start saving movie frames" switched on by default, dramatically slowing down the example runs. Now it is switched off in all example XML files.
