Refactor listen in terms of start.

Fixes #1034, at least for start and listen.

Various Input and Focus fixes

Allow travis/test.sh to be run locally (not on travis)

Require a Key on Input.

Simplify the API for Focus.at() and Focus.moveTo().
Fixes #236.
This will require an e-mail to flutter-dev.

Make Input grab focus onTap not onPointerDown.
Fixes #189.

Complain when you use Focus.at() with two different GlobalKeys that
are both in the tree at the same time.
Fixes #181.

Add dartdocs for Focus.moveTo() and Focus.moveScopeTo().

This helps people check that all the tests will pass before they send a PR.

Catch dismissable while it's animating.

Add documentation for GridPaper

I'm not actually sure what this is useful for, but I took a stab at it.

@Hixie

Fixes #173.

RenderFractionalTranslation and Dismissable

- Add RenderFractionalTranslation, a render box that does a
  translation based on a FractionalOffset.

- Make FractionalOffset more like Offset
  - dx/dy instead of x/y
  - add /, ~/, %
  - add .zero

- Add alongOffset and alongSize to FractionalOffset so that you can
  easily apply FractionalOffset to Offsets and Sizes. (Better name
  suggestions welcome.)

- Add transformHitTests boolean to RenderTransform (also on
  RenderFractionalTranslation), and to classes based on it.

- Remove the fade from Dismissable. We can add it back using the
  builder-with-child pattern like Draggable if we need it. See #1003
  for tha feature request.

- Rename a bunch of variables in dismissable.dart.

- Change the test for dismissable to not handle leftwards dismisses
  one pixel different from rightwards dismisses, and cleaned up the
  resulting effect on the test (mostly making sure we had the right
  number of pumps, with comments explaining what each one was).

Fixes #174.

Make TabBarSelection a widget

TabBarSelection is now expected to be an ancestor of its TabBar and TabBarView.

remove noSuchMethod hints

fix analysis errors and warnings in the stocks example

Add a doc comment for Performance's repeat()

Link Curve to Curves in doc comments

Less tree walking for compositing bits updates.

How's this?

Update RenderPositionedBox documentation.

Remove redundant typedef

Generate docs for more of our packages

Forgot to add the file

This is a png version of the flutter logo generated on my desktop
from the SVG in the flutter.io repository.

TBR @hansmuller

I also stopped pushing docs to domokit.org I presume we
were doing that to not break old links.  @abarth

Fix travis builds and linter warnings

Add a 'flutter ios --init' command that fetches the Xcode project from the cloud and configures it for a given flutter project

Add a 'flutter ios --init' command that fetches the Xcode project from the cloud and configures it for a given flutter project

Use the same technique for updating compositing bits as layout and
painting. This avoids walking the entire rendering tree when all you
need to update is a small subtree.
