With the 4.x-introduction of Windows the previous method for color picking was no longer working. This PR uses the following approach to reintroduce color-picking. When the Color-Picking-Button is pressed, a quasi-screenshot of the Window-content is created and displayed in a new Popup-Window. This new Window allows selecting colors by Mouse-Click. A Preview of the targeted Color is also displayed.
