Item view: don't do a zoom animation
The zoom animation in all 3 views looks very glitchy, because icons that were already in view animate, those that weren't don't animate giving weird effect. In the list view mode, the tree view branches don't animate either, showing weird holes between the branches
Also, while zooming in and out very quickly, is possible to have the selection rectangle somehow unsynced with the items sizes leading to visual glitches.
Without an animation, zooming the view feels much faster and robust giving immediate feedback when zooming via ctrl+scroll or by dragging the slider around
