@abarth

rev engine

Fix formatting issue

@Hixie

Fix build breakage

Split out Instrumentation logic from WidgetTester

This will allow writing tests/benchmark which want to use
the engine's default beginFrame and normal passage of time.

@Hixie

Always import our packages when analyzing.

Only set tolerance if simulation is non-null

Fixes #898

Update SoundEffectPlayer to use the SoundPool API

Tabbar view swipe

Swiping left or right in a TabBarView now changes the selected tab in the way it's supposed to.

Currently swipe gestures that start while the selection change is underway are ignored. Will fix that in a separate change.
