How may draw text such as “GoDiagram Win, for evaluation only” with floating text behavior
Just create a GoText, make it not selectable, add it to the GoView.BackgroundLayer, and size and position it the way you want. You may want to implement a GoView.PropertyChanged event handler to handle changes to GoView.DocPosition or GoView.DocScale.
Alternatively you can override GoView.PaintBackgroundDecoration to do what you want.
