commit 51fe34f90f4eb28dbefd6a1e4eb616da60c74b6c

Change zoom from an lfun without going through the slider
If we change zoom from an lfun directly, we set the value of the slider by
blocking signals. This prevents the slider from rounding our new zoom value.
This fixes zoom-out not being inverse to zoom-in.
