I'd expect that in this example the upper left corner of the image 
starting from (0,0) size 10x10 gets filled with random values, i.e. the 
RandomImageSourceFilter only processes the smallRegion but in fact it 
processes the whole image. So I think the example doen't provide any help.

Currently I'm having problems with paste after applying my filter to 
roiImageFilter->GetOutput() - let's see what the results are this 
evening  :-)
