[Bug] Viewport Colorbar for PET behaves unexpectedly

[JoostJM]

Describe the Bug

When loading PET data, left-mouse click Window-Level is limited to only scale the values (i.e. it always starts from 0), i.e. the window width is updated and window center kept at window width / 2.
However, when showing the colorbar in the viewport and dragging on there only allows to change the center, and not the width. This means that you can scale the image that way, and the colorbar doesn't start from 0 anymore.

Steps to Reproduce

1. Load the PET-data case in OHIF viewer.
2. Show the colormap on the PET data (e.g. the cornal MIP or any of the PET viewports).
3. Try and change the window level by click+dragging on the image (works as expected).
4. Try and change the window level by click+dragging on the colorbar (works exactly opposite).

The current behavior

See steps to reproduce. Color bar behaviour is exactly opposite from window-level on the image

The expected behavior

Window-level on the colorbar should follow the behaviour of the window-level tool on the image.

Yeah I see what you mean, we should not allow step number 4
