This patch makes three API changes:
* The dart:ui library now always communicates in physical pixels. The
framework is responsible for converting to whatever logical coordinate
system it wishes to use.
* The textBaselien property is now on TextStyle rather than ParagraphStyle,
which will let us choose which baseline to use on a per-span basis rather
than on a per-paragraph basis.
* This patch also removes the old MojoServices function endpoints.

Fixes https://github.com/flutter/flutter/issues/1360
* Added drawArc to Canvas.
Added a way to call SkCanvas::drawArc from Dart. This method is
optimized for the arc case and should be faster that drawing paths.
* Removed implementation details from docs.
* Added more details to the docs.
We used to be able to toggle observatory via a command line flag. But now, we enable or disable observatory based on the Flutter product mode.
This also allows us to fix an issue where the —non-interactive flags was being hijacked by the Dart initialization logic to enable or disable observatory. However this flag was orignally meant for the standalone runner to launch either to run tests or to run a full graphics enabled window on the desktop.
After this patch, Flutter apps on Fuchsia can access their asset
bundles. Unlike other platforms, the asset bundles are stored in memory
rather than in the file system.
This patch abstracts where the content of the zip file is stored.
Currently, zip files are stored in the file system, but in Fuchsia,
we're going to store them in memory (at least for the time being).
Rather than represent a zip file as a path in the file system, we
instead use an UnzipperProvider, which can create zip::UniqueUnzipper
objects on demand.
* Move all private config information from skia_config to skia_library_config. This was causing most skia specific defines to be applied to all targets that depended on Skia. These defines were only used by the Skia implementation. Makes the command line invocation for our sources smaller and less confusing.
* Removes defines not present in the current Skia sources.
* Dont add both directories containing SkUserConfig.h from ext and the Skia sources. Depending on the order in which the config directory was specified on the command line, the sources would use a different config.
In older versions of Skia, there were two files named SkFontMgr_fontconfig.cpp.
We want to use the one that contains SkFontMgr_FCI. That file was renamed
to SkFontMgr_FontConfigInterface.cpp
This caused the assert in https://github.com/flutter/flutter/issues/5694
We could get into a situation where the second time we rasterize a picture for an SKP, the raster cache detects that the same picture is being repeated in subsequent onscreen frames and then proceeds to rasterize the contents to an offscreen texture. This not only causes an unnecessary cache entry, but also shows the cached image in the final SKP trace (which is not what was originally displayed on screen).
runtime/BUILD.gn and ..core/BUILD.gn use flutter_runtime_mode which
is defined in common.gni. If the build comes through common/BUILD.gn
this is imported (implicity) but builds that depend on specific
files, like the Fuchsia build, won't have this imported. This
imports the gni from the build files that use it instead of relying
on it already being there.
* Add config properties to specify snapshot blob file names.
This adds the ability of the shell to override the default
dart aot snapshot blob file names, and it wires up Android's
FlutterMain to recognize the properties in the app's manifest.
This will be used for flutter applications that build their
binary snapshots into files other than the default ones
that the engine uses.
