Level Tool

[Robert Schleif]

The documentation says that it is possible to zoom an image while using the Level Tool. I don't find it possible to do this.

For transformations that use the mouse scroll wheel to control a slider (e.g. Paint where it controls the brush radius), you need to hold down the Alt key for the mouse scroll wheel to zoom instead. While this also works for Level, it should not in fact be necessary and I have fixed this for the next release. The same issue also affected a number of other transformations as well and I fixed them too.
