Remove Material's opinion about background colours, since in fact the background colour varies dramatically with the kind of material involved.

Also:
- give users of Material who previously relied on Material's defaults
  opinions about background colours
- reindent stock_row.dart
- import colors as colors in example/widgets/styled_text.dart, rather
  than in global scope, for consistency with other files
- import typography as typograpyh in example/widgets/tabs.dart, rather
  than in global scope, for consistency with other files
- make flat_button actually be transparent by not painting a
  background, rather than painting 0x00000000. This is the what I
  actually originally set out to do here.

I ran this and fixed some of the warnings flagged:
cd ~/dev/mojo/src/sky && find engine/core/painting sdk/example sdk/lib -type f -name '*.dart' | perl -nE 'chomp; local $/ = undef; open(FILE, $_); my $file = <FILE>; print $file; next if $file =~ /^part of/om; say "import \"$_\";"' > all.dart && shelldb analyze all.dart 2>&1 | grep -v 'sky/all.dart'

Then I loaded the affected examples and fixed any bugs I found from running them.

Major change to SDK:

- Fix RenderPadding to get a valid size when it has no child (it was
  previously sizing itself too small by the padding amount).

Minor changes, mostly to examples:

- Fix the 'part of' lines in sky_shell_dart_controller_service_isolate
  to match the library name given in main.dart.

- Remove unused imports in various places.

- Fix example/game/lib/texture.dart to use the new Rect creation APIs.

- Remove unused code in example/mine_digger/lib/main.dart.

- Fix example/raw/hello_world.dart to use the new Size.center API.

- Fix example/rendering/baseline.dart and
  example/rendering/justify_content.dart to have readable text.

- Fix compile error in example/rendering/transform.dart.

- Extend the debugDoesMeetConstraints() method to print useful
  information when it will be used to fire an assert.

- Remove a warning about abstract methods on RenderView that would for
  some reason only sometimes get flagged by the analyzer.

We need the material design icons at build time in order to build Sky
application bundles that include the icons. Therefore, we need can't wait until
runtime to download the icons.

Also, rather than copying all the icons into each out directory, we just
symlink to the copy in the source tree.

This script consumes a sky.yaml file and produces a bundle that contains the
listed material design assets as well as the snapshot binary. This script isn't
wired into the build system yet because we don't yet download the material
design icons using DEPS.

to the Material spec:

Added a TextStyle attribute to EditableText and "themed" the text style for Input.

When navigating from one app to another, we create a new Android window and
destroy the old one. Previously, when we destroyed the old window after
creating the new window, we would destroy the Ganesh context after making the
GL context for the new window current, causing us to corrupt the GL state in
the new window. After this CL, we call MakeCurrent before destroying the Ganesh
context so that it interacts with the proper GL context.

Fix theme changing: turns out we were not reparenting stateful surviving nodes when their parents changed identity

This also makes the optimistic/pessimistic mode switch change the active theme, because why not.

Turns out I had misimplemented Rect.center.

While I was here, I also implemented Rect.width and Rect.height (to
help avoid making that mistake again), and copied shortestSide from
Side to Rect so that we can avoid having to allocate a Size to get the
shortest side from a Rect.

By profiling mine_digger in a continuous rebuild loop, we observe
Widget#syncChild as being very hot. This CL optimizes this function by making
sure to read each input value exactly once.

Also, the hash operations for _mountedChanged were showing up on the profile,
so this CL makes _mountedChanged into a List, which should work fine.

Together, these changes reduce the amount of time we spend in Navtive code
inside the VM from 29% to 20%.

A simple container for a TabBar. It is defined by a list of
TabNavigatorViews, each of which is just a TabLabel and
the tab's content.

The content of each tab is represented by a function
that produces a Widget called "content". I couldn't
bring myself to call it buildTabContentCallback or something
else more specific.
