}

ViewPort is our view port for the image being edited. It's a specialized widget that will display the image according to zoom / window select.

It is both a CanvasObject and a WidgetRenderer -- the abstractions in Fyne are not clear, but when those were implemented it worked (mostly copy&paste code).
