Comment 1 for bug 83190

I have committed a change that sets proper gtk.Range increments for the slider. To get it to the centre again you can now drag it all the way to the left or right, and then click in the centre of the slider. This makes it jump from 1.0 to 0. If you're not all the way at the edge it will jump from 0.9 to -0.1 which would not be the exact centre. You can also move it with the arrow keys now. There are 20 steps across, so if you hit the arrow key 10 times, you will get to the centre. Once we are out of the string freeze I will add a tooltip/status bar message to let you know what value you are currently on.
