Each layer is supposed to reexport the parts of the previous layer
that are part of its API.
- In painting.dart, export from dart:ui all the Canvas-related APIs
that make sense to be used at higher levels, e.g. PaintingStyle.
- Delete painting/shadows.dart. It was dead code.
- In rendering/object.dart, export all of painting.dart.
- In widgets/basic.dart, export all of painting.dart and
animation.dart. Some classes in animation/ are renamed to make this
less disruptive and confusing to the namespace.
- Split out Stocks back into an import model rather than a part model,
so that it's easier to manage its dependencies on a per-file basis.
- Move Ticker to scheduler library.
- Remove as many redundant imports as possible now.
- Some minor nit picking cleanup in various files.

Flutter can play sounds using this package. However, when Mojo Shell is running Flutter, it lacks the necessary media service.
This patch creates a hook to the mojo binary `media_service.mojo`. If Mojo Shell is built with this media service, then it will be able to play sounds when running Flutter.
The names are probably less familiar, but more consistent:
- FrameCallback: a callback that is relative to the frame and wants the
frame offset (a duration) as argument.
- addXFrameCallback: adds the given callback to the internal lists/maps.
- scheduleXFrameCallback (currently only X = ""): add the callback, but
also trigger a new frame.
- handleX: the method that is invoked when the event-loop or the frame
calls into the scheduler.
- ensureXYZ: ensure that the callback happens.
Unfortunately there is the ambiguity between a "callback": it can be a
closure, or the action of doing a callback, so we end up with:
ensureBeginFrameCallback, and ensureEventLoopCallback, where
"callback" means the action of being called back.
Other changes in this patch:
- Make the 'flutter' tool say "Updating flutter tool..." when it calls
pub get, to avoid confusion about what the pub get output is about.
- Make the bash flutter tool call pub get when the revision has
changed. (This was already happening on Windows.)
- Fix a raft of bugs found by the analyzer.
- Fix some style nits in various bits of code that happened to be near
things the analyzer noticed.
- Remove the logic in "flutter test" that would run "pub get", since
upon further reflexion it was determined it didn't work anyway.
We'll probably have to add better diagnostics here and say to run the
updater script.
- Remove the native velocity tracker script, since it was testing code
that has since been removed.
Notes on ignored warnings:
- We ignore warnings in any packages that are not in the Flutter repo or
in the author's current directory.
- We ignore various irrelevant Strong Mode warnings. We still enable
strong mode because even though it's not really relevant to our needs,
it does (more or less accidentally) catch a few things that are
helpful to us.
- We allow CONSTANTS_LIKE_THIS, since we get some of those from other
platforms that we are copying for sanity and consistency.
- We allow one-member abstract classes since we have a number of them
where it's perfectly reasonable.
- We unfortunately still ignore warnings in mojom.dart autogenerated
files. We should really fix those but that's a separate patch.
- We verify the actual source file when we see the 'Name non-constant
identifiers using lowerCamelCase.' lint, to allow one-letter variables
that use capital letters (e.g. for physics expressions) and to allow
multiple-underscore variable names.
- We ignore all errors on lines that contain the following magic
incantation and a "#" character:
// analyzer doesn't like constructor tear-offs
- For all remaining errors, if the line contains a comment of the form
// analyzer says "..."
...then we ignore any errors that have that "..." string in them.
This patch combines embedder.dart and shell.dart into one thing. We should now
handle a bunch of error cases better.
* embedder.connectToApplication has moved to shell.connectToApplication,
matching the rest of the mojo universe.
* embedder.connecttoService has moved to shell.connnectToService (and merged
with shell.requestService).
* shell.requestService is now shell.connectToService, matching the rest of
the mojo universe.
* serviceRegistry has moved from embedder.serviceRegistry to a top-level
getter.
Fixes#1803
We were assuming that the text extended from 0.0 to its max content width.
That's not correct for right-aligned text. Instead, we need to layout the text
again at the width we want it to occupy.
