Navigation title animation problems

[martin-reiterer]

Since version 0.1.0-alpha04 it seems that the animations of CupertinoNavigationTitle and CupertinoTopAppBar.title are deferred/flickering. I've adapted SectionsScreen.kt for providing a simple example. The corresponding changes can be found in this patch file: Demonstrate_navigation_title_animation.patch

The following animation problems can be seen in the attached video:

• During the page change animation the CupertinoTopAppBar.title is displayed and CupertinoNavigationTitle is hidden.
• When the animation ends CupertinoTopAppBar.title gets hidden and CupertinoNavigationTitle gets visible.
• When scrolling behind the transluent CupertinoTopAppBar, then the divider seems to be nervous. On fast scrolling, the page titles get visible above the TopAppBar.

Navigation title is an experimental temporary api that will be replaced with large top bar in the future. To disable blinking you need to add hasNavigationTitle = true for CupertinoScaffold
