COMP: Remove unnecessary null pointer check
transform pointset according to the datanode geometry
Add callback function after clearing pointset.
No poinset interaction during update.
change order of input wanted value and set maximum
corrected to bounding box, to minimal values != 0
switching to SeriesWriter also for composite types

* updating comments, better exception handling
Add a new Test for PointsetMapper2D with transformed Points
added missing call to Deactivated method of superclass
seriesdata is not saved to a member anymore. because qwt handles its destruction
symbols have to be passed as pointers
Disabled 2D and 3D ToolSelectionBoxes if segmentation is invisible
Since Widget is enabled according to toolmanager state there is no need to do it here. Also this lead to wrong calls of (un-)register clients on the toolmanager
