aspect: make video-zoom logarithmic
The past behavior was a bit weird, especially when zooming out. There
was no simple way to zoom in or out in consistent increments using
keybindings alone.
The new behavior preserves most of the old behavior's semantics but
scales out to infinity better. It coincidentally also makes it
really easy to get clean power of 2 ratios (e.g. 2x, 4x, 8x and their
inverses).
Fixes #3004.
