Steamlining the workflow in the Histogram Window

[hecklho]

In the Historam Window ist is possible to adjust the brightest point and the darkest point in the image. But if you want to check how big the areas of 0 % brightness and 100 % brightness are, then you have to leave the Histogram Windows and use the following commands:
- Display Brightest Point (CRTL+SHIFT)
- Display Darkest Point (CRTL)

It would be very helpful it the shortcuts for the displaying of the brightest and the darkest point would be available when the Histogram Window ist opended.

Another solution would be to implement two new buttons in the Histogram Window so that, by clicking on the buttons, the brightest and the darkest point could be displayed.
