RFE: visual (text) feedback of window/threshold values

[Elaine Meng]

This could apply to both the graphics window in desktop use and in VR (as requested by Dmitri).

Horos shows continuous feedback on window width/level values in text on the window as they are changed with the mouse, as well as zoom and a few other things. Continuous feedback of the current values is generally useful, especially in Hounsfield units that are pretty well standardized between datasets.

Reclassify as needed.

I attach screenshots of the Horos 2D and 3D viewers. The colorkey shown in the 2D viewer is optional, but when it is shown, its numbers also adjust continuously.

The 2D viewer shows a lot of text information. The colorkey shown on the right side is optional, but when it is shown, its numbers also adjust continuously as windowing is changed. Reported values include image size (static), view size (changes as I resize the window), WL and WW (change as windowing is adjusted via mouse mode). The two lines below WL/WW change as I move the cursor within the image. Bottom left: zoom percentage, stack position, e.g. image 1 of 48 in stack (changes as the plane is changed with scrolling or by dragging the slider across the top). Don't know what most of the stuff on the right is, other than acquisition date and time. Letters along the middle of the sides indicate orientation (L left R right, A anterior P posterior).

The 3D viewer shows much less, WL/WW and the orientation letters (besides those mentioned above I inferior S superior), but the orientation cube with those letters on its faces is more useful. The stuff on the bottom right also reports orientation somehow, as it changes when I rotate the volume.
