[Vv] Window Level Fusion Slider

[Rajamani, Kumar (GE Global Research)]

Dear Simon 
Thanks for the update regarding the window/level functionality

I will do a update and then check its functionality. 

There could also be potential issues if the W/L ranges of the base image
And the W/L of the overlay image are very disparate
This might require some grey level mapping before the overlays are done 

I would like to know your thoughts regarding this
I shall test it with this version and let you know my results

Warm Regards
Kumar

Hello,
I noticed that the window/level of the fusion was not accounted for. I
have tried to correct on the cvs version. Let me know if you have time
to test it !
