Original issue's description:
> [Mac][Material Design] Fix toolbar height on Retina.
> 
> A recent change to center the toolbar's buttons and textfield on
> Retina displays throws them off-center on Retina when in Material
> Design. This change bypasses the adjustment in this case.
> 
> Note that on Retina there is an odd number of pixels between the top
> and bottom edges of the toolbar, which means that the location bar's
> contents cannot be exactly centered. This is per spec (it also
> occurs on ChromeOS).
> 
> Lastly, this cl makes the location bar shadow color transparent.
