Previously we reversed the event path by mistake before dispatching events.

defaultHitTestChildren should return whether it hit something

Some clients want to know whether they hit their children.

Fix minor problems in _ScrollGestureRecognizer, Dismissable, lerpColor

Alternating scroll gestures would sometimes be ignored because _ScrollGestureRecognizer didn't always reset its _state when the pointer[s] went up.

A Dismissable dismiss triggered by a drag and then a fling could cause the next attempt to drag-dismiss to fail.

Fixed the definition of lerpColor().

Adds power bar and movements to boss fights in demo game

These functions are now in sky:dart.

RenderFlex should handle overconstrainted constraints

Disable reparent during sync

This feature is causing a bug because the widget tree isn't correctly
synchronized with the render tree.

Rather than reading out the maxWidth, we should call constrainWidth to factor
in the minWidth, which might be bigger.

Change documentation for how to log using sky_tool

Actually make the raw examples work again

In my previous patch, I forgot to fill in the other diagonal entries in the
device transform matrix.

Remove all clients of sky.view.picture

Everyone uses sky.view.scene now. This patch also cleans up the raw examples
and makes them follow a consistent pattern.

Guard IOSDevice logs

Add sky_tool logs command

Initial boss fight in demo game

Improvements to demo game

Move widgets and rendering inside src

Improves on demo game balance and adds levels for lasers

Code outside of package:sky should import this code using

package:sky/rendering.dart
package:sky/widgets.dart

Moving this code into the "src" directory is a convention that signifies that
and it cleans up the generated dartdoc because the libraries in the src
directory aren't included in the generated documentation. Instead, the classes
are documented in the widgets.dart and rendering.dart libraries.
