Histogram for adjusting levels from the button #3128

Description

Description

When clicking on the window leveling button, a window with a histogram could be displayed with minimum and maximum sliders (and perhaps text input slots) for adjusting the levels.

Scenario

One could use this to easily adjust levels for visibility of the image.

Rationale

In most image visualisation programs I am familiar with, it is customary to show a histogram of all pixel intensities, and have a slider (plus text slot for specific input) for minimum and maximum display values. Something similar is already in ilastik when one right clicks the raw data to adjust levels, but having it easily accessible would be great. This could be in addition to the current ilastik mouse mode, or so that one can quickly move back and forth between labeling and modifying the display values.

A bonus feature that would be really nice is if gamma could also be adjusted in this way.
