	I would _really_ like to see includes done like
#include <VTK/Filtering/vtkDataSet.h>

Which in my mind helps segregate the vtk includes from other includes  
in my source codes, helps me figure out which libraries I need to  
include and makes the compile command line WAY shorter since I don't  
need a bazillion include directories, I need just one for VTK plus any  
others for the 3rd party stuff.

I think as much as I would like the above that there might be issues  
with that setup due to how some scripts generate code... I think..
