Scrolling with mouse broken in 0.4.4
This commit should be reverted. 0720525f
Which means, so should this one: f9e50857
With these commits, mouse ctrl+wheel zooming is broken. It works backwards (ie, scroll up and it zooms out, scroll down and it zooms in), and jumps way too much between each wheel "click".
Please revert those commits and restore the previously working functionality.
