Prerolling the rasterization tasks reduces the number of render target
switches because we don't interrupt the main render target.

Experiment with caching rasterized layers

This patch adds back (and tweaks) some code that we previously removed
for caching rasterized layers. Now that our layerization code in the
framework is more sophisticated, we should be able to get more value out
of this mechanism.

Initial work toward exposing the Java native interface APIs in Dart

Update name and link

Bump sky services version to 0.0.76

First steps toward GCM support

New gcm mojo service with Android implementation.

Temporarily checking into flutter repo until it's easier to add third
party services.

Introduce Canvas.transform

Include the class name in the IMPLEMENT_WRAPPERTYPEINFO macro expansion

Canvas.transform is the same as Canvas.concat, just with a better name.

Fixes #1080

This allow multiple uses of IMPLEMENT_WRAPPERTYPEINFO within a source file

Add Tonic macros for dispatching to static methods

DartArgIterator was starting at argument index 1 because it assumed that the
arguments include a pointer to the "this" object for an instance method.
DART_REGISTER_NATIVE makes the same assumption in the argument count.

This change adds versions of the macros that are suitable for static methods
with no implicit arguments.

Add direct wrappers to tonic

Instead of using a C++ object as a peer to the Dart wrapper, these wrapper hold
arbitrary data in the internal field of the Dart wrapper.

Shared build configuration for Mac/iOS build targets on bot

Fix android BUILD.gn to match Chromium's latest.

Also disable proguard. It's unnecessary and breaks compilation of GCM
(in a separate patch).

Initialize the global dart library natives separately and outside the isolate create callback

rev engine

Update Skia revision

Fix typo in application identifier

Don't destroy the engine when detaching from the window

Reading the Android docs, it sounds like an android.view.View can re-attach to
the window after detaching. Previously, we destroyed the engine when we
detached from the window. Now we wait for the activity to be destroyed.

Hopefully fixes #997

Account for the removed endianness check on Mac and fix the context creation routine in skia_utils_mac

Hook up wordSpacing and per-inline lineHeight.

Change line-height to use percentages rather than pixels.

Unhook packages/material_design_icons from the build

We don't have any use for this symlink in the out directory anymore.
This patch lets us remove our fork of build/symlink.py.

Remove RuntimeEnabledFeatures
