From: Sean Paul <seanpaul at chromium.org>
Upgrade the tiny box in the top left corner to some vertical color
bars with horizontal grey and white bars at the bottom.
v2:
- Removed hardcoded bar heights
- Made number of vertical bars configurable
- Fill in the entire screen horizontally
v3: (Bhanu)
- Rebase
- Drop static variable
