- Fix edges theme data to not use a rounded rect path for canvas material.
- Add debugging hooks for TextStyle, and fix a warning.

Animate checkboxes. I based it on the dialer app. Could probably use more improvement, but I think this is an improvement on what we are doing currently.

This is a completion of Hans's WIP patch:
https://codereview.chromium.org/1176133002/

Makes it possible for us to style text in fn2 apps.

The title style in the toolbar doesn't look quite right
but as far as I can tell its the same color as the
old typography code produced.  Will need further investigation.

Fixes #213

Make Material actually create material, with opinions about what that
means.

Make FloatingActionButton use this.

Make Scrollable use this.

Make BoxDecoration support drawing a circle instead of a rectangle, so
that floating action button doesn't need a custom painter.

Implement RaisedButton (and remove button.dart, since there's no
"button" in Material Design).

Make InkWell have a "child" argument instead of "children", and not
have it introduce a Flex into the hierarchy.

Update container.dart example. Clean up some imports.

Previously, it would always try to be as big as possible. This CL fixes a
problem with the search bar whereby the text wasn't centered. Now the Stack for
the text sizes its height properly and then becomes centered.

This moves input.dart to editing2/, since that way we can define the layering as strictly unidirectional.
It also reorders a bunch of imports to fit the style guide.
I removed the old remnants of the widgets example, and put the fn2 examples into the examples/widgets/ directory, to parallel the framework directory names.

* Cherrypick crrev.com/333293 (freetype -> freetype-android).
* Update mojo/go/go.py to use android-16 (NDK API level 16), which is
  4.1 (first Jelly Bean). Chromium dropped support for 14.
* TODO (separately): also update tools/go/upload.py and upload new
  binaries?
* Roll android_tools (to match Chromium).
* Small fixes to match //base changes: base::ObserverList, TraceConfig,
  ThreadTicks, etc.
* Restore build/ls.py (and add it to the list of files to not roll).
* Remove the dependency on third_party/instrumented_libraries.
* Add "enable_topchrome_md = false" to build/config/ui.gni.
* Add build/config/ui.gni to files_not_to_roll in
  update_from_chromium.py. (We should probably get rid of the use_glib
  variable/argument, and others as well.)
* Remove mojo/tools/roll/{roll_network_service.py,
  roll_network_service_patches/network_service.patch}. These are for
  rolling from Chromium, whereas we now have/use monet.
* Roll buildtools (to match Chromium).
* Modify sanitizer gn/gni files to make it work (patch included).
  (Maybe the patch even works -- I haven't checked.)

This isn't perfect, since it makes non-minimal modifications
to the yaml and xml files.  In the yaml case it sorts the keys
and in the xml case it doesn't do the fancy attribute wrapping,
but this seems good enough to use.

Dispatch events to fn nodes for each RenderObject that the event goes through, instead of starting at the innermost target and just propagating through our tree.
This starts laying the groundwork for fn disconnected subtrees that are linked together into one RenderObject tree.
