Metal style when processing: Line of white pixels over spinner

[neoneye]

This is what I'm seeing with the demo project

It goes away if I briefly switch to Adium style and then back to Metal style.

I think the spinner is layouted using the _indicatorRectForBounds:, but can't figure out precisely whats wrong.

I fixed this by adding a new macro:

#define kMMTabBarIndicatorHeight 15.0

And replacing the instance of kMMTabBarIndicatorWidth in MMTabBarButton.m and MMTabBarButtonCell.m with it that affect the height.
