When setting "reverse scroll direction" in the mouse settings, this affects the touchpad as well, however there is no mention of this in the configuration pane.

Reproducible: Always

Steps to Reproduce:
1. Enable reverse scrolling under the mouse settings
2. Use touchpad scrolling on a big page in a small browser window

Actual Results:  
Scrolling is reversed (except for horizontal, but that's a different bug)

Expected Results:  
Any of the following:
- system settings should allow separate configuration of reverse scrolling for mouse and touchpad (and joystick?)
- reverse scrolling should be a separate configuration pane, (e.g. Natural Scrolling)
- Touchpad should have a checkbox for reverse scrolling as well, which gets its settings from the mouse checkbox.

I was looking for Natural Scrolling, which is very easy on OS X and Gnome, but took me quite a while to find on KDE.
