It made more sense for me to group the tests via input rather than via
direction of zoom, so I made a test each for pinching and wheel event
zoom. I can change this though if there's some reason for grouping them
that way that I'm missing.
From what I can tell, resetting the zoom happens via the hand tool,
which is already tested, or via the UI, which should be E2E tested.
Couldn't figure out how to write a test for that.
