Comment 2 for bug 3644

1) Start gedit
2) Turn off "word wrap" from "edit" - "preferences
3) Type something really long so that a horizontal scrollbar appears
4) Position your mouse cursor on the text area
5) Move the mouse scroll wheel up/down

Problem: nothing happens!

Suggestion:
1) If a scrollable control only has a horizontal scrollbar, moving the mouse wheel should scroll horizontally
2) If a scrollable control has both horizontal and vertical scrollbar, moving the mouse wheel should scroll vertically BUT adding a modifier such as SHIFT should scroll horizontally (Inkspace uses SHIFT to scroll horizontally)
