When zooming with Ctrl+wheel, used fixed-factor steps instead of scroll wheel rate information. Fixes #9177. Important Notes - Wheel events are distinguished from trackpad gestures, so that OS X pinch-zoom still works nicely. - When zooming with the mouse wheel, scale factor is rounded (geometrically) to the nearest power of √2, and then stepped up or down by the same factor; this ensures that round values like 100% are never skipped over. - Added directed-clamping logic, so that if the zoom is moved outside the clamping range of a zoom-method, it can be stepped back into range without jumping.
