1/2 split view doesn't seem to scroll via touch, but works with the mouse wheel.
I wonder if this has something to do with scroll lock in the apzc. When in split view, I can select tiles horizontally, but can't scroll up/down. Once I resize to normal view, I can vertically select tiles, and can scroll horizontally.

Attached patch patchSplinter Review
Well, that was simpler than I thought.  Our stylesheet explicitly disabled vertical scrolling on about:start, but this had no effect on touch scrolling until bug 942995 was fixed.

This patch just swaps the overflow properties when we switch to the vertical layout.

Went through the following issue for iteration #21 without any issues. Used the following builds:

- Ensured that the about:start screen scrolls horizontally when Firefox Metro fills the entire width
- Ensured that the about:start screen scrolls vertically when Firefox Metro fills the screen 1/2
- Ensured that resizing the Firefox Metro window appropriately reshuffles the tiles under about:screen and the correct scrolling is being used (vertical/horizontally)
- Ensured that you can scroll through websites by swiping vertically while Firefox Metro is using 1/2 and other width sizes
- Ensured that scrolling via mouse wheel/touch works without any issues
- Ensured that all of the above test cases work with both left & right sides of the screen

There's several issues/improvements I noticed when resizing the Firefox Metro window when going through this bug. I will create separate tickets as this just concentrates on the scrolling aspect.
