LiveInteractiveViewer class abstract

An InteractiveViewer where the transformation is exposed as a cell.

The value of the transformation cell is updated whenever the user scrolls, pans or zooms the widget.

Setting the value of transformation results in the widget being scrolled, zoomed and panned to the position represented by the transformation matrix.
