[CHANGE] tools directory in TransferCalc was an old copy and is deprectaed. Replaced by link that ensures use of the latest module specific tools.

[FIX] Use osg::Matrixf instead of osg::Matrix

[FIX] fiber stipples finally work now; there might still be a problem with the texture lookup at the voxel positions

[FIX] fiber stipples now actually render stipples again; there is still a problem with stipple directions

Previous commitment had some bug fixes. But it also said that some bugs dealing
with the surface segmentation still remained. This commit fixes them. The
errors consisted of not initialized member variables in some classes regarding
point instances of parameter space clustering and boundary detection.

Regarding the module "Surface detection by Lari" crashes appeared sometimes.
The reason was that the object containing the status bar thing (point classifier
class) was deleted before the progress was set to be finished.

Remaining bug:
The following bug could not be fixed short-time because it does not appear if
the module is compiled using the debug flag.
Shortly said sometimes the search instance even can not find a point using
coordinates of itself. Weird. I put setting the ID in the end of
WLariBruteforceClustering::addExtentCluster manually at least not to get stuck.
But still some groups result a bad result. No errors appear when compiling (cmake)
using the debug flag. Has to be fixed sometime later.

Having forgotten to commit memory bugs previously. Changes are commited here.
