The TabBarSelection change animation needs to start where the fling's drag gesture ended rather than from zero. The intial vlaue of progress for the TabBarSelection's performance is now converted from the range used during an interactive drag, to the range used when animating from the previously selected tab to the new one.
TabBarSelection now requires a maxIndex parameter.
This matches the naming pattern expected from package:test
`flutter test` doesn't care, since it finds all _test.dart
files and runs them regardless of directory.

- Remove unused FocusChanged typedef.
- Remove unused centerOfAttentionHeroTag.
- Modernize static functions for interacting with Scrollable by moving them
into the Scrollable class.
Add BoxConstraints.isNormalized feature.
Use this feature in asserts in all the intrinsic dimension methods, in
various relevant BoxConstraints methods, and in layout().
Wrap the _DebugSize logic in BoxConstraints.constrain() in an assert
block to avoid a branch in release mode.
Remove the logic in BoxConstraints.isSatisfiedBy() that dealt with
non-normalized values.
Add BoxConstraints.normalize().
Make RenderCustomOneChildLayoutBox.performLayout() only set
parentUsesSize on the child if the constraints aren't tight.
I had to add a setLocale method to WidgetTester and
split the code in FlutterBinding which handled locale
changes to allow me to dispatch a locale change w/o actually
changing what the c++ code reports as the locale.
Also added the test to Travis.

Factor out a reusable interface called Decoration from BoxDecoration.
Make all the consumers of BoxDecoration and the erstwhile BoxPainter
into consumers of Decoration.
Make a BoxPainter be something you get from a Decoration, rather than
something to which you pass a BoxDecoration.
Rename Shape to BoxShape now that it's documented specifically as
applying to boxes.
Move EdgeDims to its own file.
Move FractionalOffset up so that it's with the other helper classes in
its file rather than alone at the end.
Minor change to RenderClipOval's hit testing to avoid taking an
unnecessary square root.
Rename BoxDecorationPosition to DecorationPosition since
RenderDecoratedBox now takes any Decoration.
Implement hit testing for rounded rects.
Rename AnimatedBoxDecorationValue to AnimatedDecorationValue, and make
it support lerping across any Decoration (by deferring to the objects
involved).
Users of MaterialApp can provide an onLocaleChanged handler that will be
called to asynchronously fetch locale-specific data. MaterialApp will
then instantiate a LocaleQuery that supplies the locale data to its
descendants.
Instead of PointerInputEvent having a "type" field, we now have a
different class for each pointer type.
This has ripple effects throughout the system.
I also did code cleanup in affected files while I was there.
Also:
- minor code reindents in places.
- reset the widget tree between tests.
- once you generate a route, don't let its builder change
(previously it would keep changing as the routes table changed).
- revert the stocks app toolbar-fading-on-forward-transition thing.
This patch restructures how we handle drawer. The drawer is now a child of the
Scaffold, which wraps the Drawer in a DrawerController. The DrawerController
manages the interaction with the navigator as well as the edge swiping. The
DrawerController's state machine is driven almost entirely off its Performance,
which it now owns completely.

This patch integrates Mimicable with Overlay such that you can tell a Mimicable
to lift up into the overlay and animate towards another widget identified by a
global key.
Heroes with the same tag have to have keys that are unique across the
entire subtree. Since we can now show both stock lists, this means we
have to include the tab in the heroes' keys.
Fixes#668.
The TabBar's selection is now represented by a TabBarSelection object which encapsulates both the previous and currently selected indices and the Performance used to animate the selection indicator.
Added a TabBarView class which displays a tab's contents. It uses a shared TabBarSelection to stay in sync with a TabBar. The TabBarView scrolls in sync with the TabBar when the selection changes. Eventually it will allow one to fling the selection forward or backwards.
Added a tabBar property to ToolBar. Typically the corresponding TabBarView will be the body of the toolbar's Scaffold.
Removed TabNavigatorView and TabNavigator.
Added a widget gallery tabs demo page. Removed the old tabs demo.
- These controls now have proper radial reactions.
- You can drag the switch.
- The radio button animates properly.
- There's a demo in the Material Gallery
