Description

Steps to reproduce:
1. Compile and run attached .MXML file or .SWF file
2. Note that only 8 of the 10 items are displayed, but there are no vertical or horizontal scroll bars.

Actual Results:
No scroll bars are displayed. Since the direction is vertical, new columns are added offscreen and therefore we should get a horizontal scroll bar. Unfortunately, it looks like ScrollControlBase sets the horizontalScrollPolicy to "off" (ScrollPolicy.OFF) by default.

Expected Results:
The horizontal scroll bar should be visible (and set to auto by default – or possibly just overridden to auto in TileList class).

Workaround (if any):
if you set the TileList control's direction property to vertical, you need to set the horizontalScrollPolicy to "auto" or "on"
