In ScaledView, panning should be restricted like it is also done in Viewport.

At the location here:

if the pixmap left is outside of view, and right is inside, shift so that right is at boundary
if the pixmap right is outside of view, and left is inside, shift so that left is at boundary
top/bottom accordingly

Maybe scaler.map(pixmap->rect()) and use contains() on sceneRect() to determine four bools, then use above logic.

Also ignore mouse movement outside of the pixmap. It can have irritating effects.
