Summary:
NavigationCardStack is a custom component, and its API should be explicit, not
too generic..
In NavigationCardStack, the prop `renderOverlay` is actually used to render
the NavigationHeader, and we uses absolute position to build the layout for
the header and the body.
One of the problem with using absolute postion and fixed height to build the
layout that contains the header is that the header can't have variant height
easily.
Ideally, if the layout for the header used flex-box, we'd ve able to be more
adaptive to deal with the header that has variant height.
That said, let's rename `renderOverlay` to `renderHeader`, then build the
proper layout that explicitly works better with the header.
If we to need to support overlay in navigation, we may consider add
`renderOverlay` later, if it's really necessary.

Summary:
The animation shown in the UIExplorer example for NavigationExperimental's NavigationHeader is not working correctly. Due to an incomplete use of the `renderTitleComponent()` callback, interpolation is not working correctly in this example.
Even if the animation error is subtle, since the examples are followed by developers quite closely, the bug may multiply if not corrected in the sample code.
This is a really *tiny* modification that fixes that particular animation.
