[vtkusers] Controlling the intensity and brightness of two images and blending them

[Anka Kochanowska]

Hi!
I am doing it for om\ne of the blended images. I use 
vtkImageMapToWindowLevelColors and set window and level. In my case I 
set it before blend and never change it later, so I do not know if it is 
a good idea.
