Autorange and Curve Control display

[tomczak]

In Autorange, the Curve Control is displayed but can't be changed manually. I wonder if it would make sense if it could (e.g. Auto checkboxes and Thereshold sliders would be zeroed or grayed-out if a manual change is made in the Curve Control and be restored to Auto if they are checked)?

The Curve control has an Autorange command in its Settings menu, so if you use Brightness Curve, for example, you can set the curve to autorange and still be able to edit it afterwards, so this functionality already exists.
