What does the histogram tool display in each display mode of a transformation ( input, preview, split screen).
For example:
- in split screen display, the histogram appears to display the preview histogram. In this mode, when the input image is probed using the mouse, the preview histogram is marked with the probed pixels highlighted in red.
- if in a cropping transformation, where the cropped zone contains a limited number of HSV-V values : when probing the input image outside of the crop area, some gray markers briefly appear, but they do not accumulate nor show in red.
See screen capture below.

It could be useful to enable two histograms displayed together: the input image histogram and the preview image histogram.
Moreover, probing markers for input and preview images could then be displayed over their associated histogram.
