This is being added, because testing the latest `develop` version for `fyne` fails with the following error: ``` ui/widgets/imageplaceholder.go:48:3: cannot use i.imageDisp (variable of type *TappableImage) as fyne.CanvasObject value in argument to container.NewMax: *TappableImage does not implement fyne.CanvasObject (missing method MinSize) ui/widgets/nowplayingcard.go:51:33: cannot use n.cover (variable of type *TappableImage) as fyne.CanvasObject value in argument to container.NewBorder: *TappableImage does not implement fyne.CanvasObject (missing method MinSize) ui/widgets/tappablewrappers.go:64:21: cannot use t (variable of type *TappableImage) as fyne.Widget value in argument to t.ExtendBaseWidget: *TappableImage does not implement fyne.Widget (missing method MinSize) ```
