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

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.

Add an icon to the Flutter Material Gallery

@abarth @hixie

Add an icon for the Stocks app.

Not great.  Better than nothing.

@hixie

Fix `flutter apk` to work with resources

I screwed up my last change, turns out the package command
is sensitive about having all of its flags before args.

Also made it possible to control the resources directory
from the command line per the review comments in the previous change.

Correct the TabBarView swipe selection change animation

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.
