Fix Color Picking

Browse source 
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.
