[bugfix] Use correct matrix for scaling.

Browse Source 
For some of the scaling approaches the wrong matrix (dereferenced
nullptr) would have been used which should have resulted segmentation
faults. With this commit we add a method getMatrix() that returns the
correct one and use that for scaling.
