Comment 12 for bug 527267

For Ambiance the situation is much better - still wider then toolbar buttons but the fix allows me to fit two more toolbar buttons in the space that was vacated by narrowing the indicator width for 4 indicators.

I'm pretty its safe to remove 2 or 3 more padding pixels from each side of a notification icon - the widest icons (like the battery meter) has about 4 pixels padding from each side.
