[Vv] Window Level Fusion Slider

[Simon Rit]

Dear Kumar,
Wrt to the w/l of the fusion image, I totally agree and that's why the
guy that developed this functionality has added specific text boxes
for the w/l of the fusion image. If you open an image and add a fusion
image, go to the overlay tab and you can set the w/l of the overlay
image. Therefore, the w/l of the image and it's overlay are totally
independent.
Let me know if you feel that it's not enough,
Simon
