This returns us to a more stocks1-like arrow style.
Also it uses math rather than transforms to rotate the arrow, since transforms are expensive.
It also removes the save/restore calls, which are _really_ expensive.
Also some minor style fixes.

The relayout subtree root concept is intended to handle the case where
a node, when it lays itself out for a second time, changes its opinion
about what dimensions it should be. In such a situation, the parent,
if it based its own opinion about what size _it_ should be on the
child's dimensions, would also need to lay itself out again. Thus,
when this scenario is possible, the child remembers the parent, and
when it would be told to relayout, we actually start the layout with
the parent.
In practice, this chains, and we end up with nodes that point to
ancestors ten or more steps up the tree such that when the inner most
child re-lays-out, the whole app ends up relaying out.
This patch tries to short-circuit this for the case where the
constraints being applied to the child are such that actually, the
child has no choice about its dimensions. In that case, the parent
can't change dimensions when the child re-lays-out.
This makes a huge difference on the stocks demo app. Without this, on
the third rendered frame, there are 72 relayoutSubtreeRoot links, the
deepest chain is 8 deep, and 9 of the chains are only 1 level deep.
With it, there are 63 relayoutSubtreeRoot links, the deepest chain is
only 4 deep, and 38 of the chains are only 1 level deep.

Currently you lose your scroll and drawer state when coming back from the settings pane.
I think we should solve this by having the Navigator maintain a Stack and
keeping the StockHome alive underneath it. But this is good enough for a first iteration.

tree of InlineStyle and InlineText elements.
StyledText builds an Inline that renders the tree.
For example this StyledText object:
new StyledText(["FOO", [boldLargerStyle, [greenStyle "BAR"], "BAZ"] BORF]);
Renders the same way the following HTML would,
assuming that TextStyles boldLargerStyle and
greenStyle were defined.
<style>
div {
display: inline;
}
</style>
<p>
<div>
FOO
<div style="font-weight:bold; font-size:larger">
<div style="color:green">
BAR
</div>
BAZ
</div>
BORF
</div>
</p>

We can't have two copies of |embedder.dart| or |shell.dart| because they take
ownership of some underlying Mojo handles. Instead of duplicating the code,
this CL makes the old locations just export all the symbols from the new
location. I've also done the same with fetch.dart to avoid code duplication.
Finally, I've removed image_cache.dart in the old location because the only
clients already live in the new world and ought to use the new location.

Some files are moved by this:
Copy framework/node.dart into types/ - preparing for framework/'s decomissioning.
Move app/scheduler.dart into sky/scheduler.dart - "app" doesn't really make sense.
As part of the SkyBinding cleanup, I made the hit-testing less
RenderBox-specific, by having the HitTestEntry.target member be a
HitTestTarget, which is an interface with the handleEvent() function,
which is then implemented by RenderBox. In theory, someone could now
extend hit testing from the RenderBox world into their own tree of
nodes, and take part in all the same dispatch logic automatically.
This involved moving all the hit testing type definitions into a new
sky/hittest.dart file.
Renamed SkyBinding._app to SkyBinding._instance for clarity.
Moved code around in SkyBinding so that related things are together.
Made WidgetSkyBinding use the existing SkyBinding.instance singleton
logic rather than having its own copy.
I also added some stub README.md files that describe dependencies.

Move app/view.dart to rendering/sky_binding.dart since it's part of the RenderObject API, really (it knows about RenderView intimately).
The tests pass. I didn't check every last example.

Buttons and menu items use onPressed. Also, don't pass along the sky.Event
because that's a lower-level concept.
I've also reordered parameter lists to put the |child| argument last in a
number of places.
Also, fixed a bug where FloatingActionButton was missing syncFields.

This also moves the test for stocks into a new tests/examples/
directory, where we can put tests that test the examples.

The underlying problem is that we lacked a RenderObjectWrapper for the
RenderView, which meant we couldn't handle changing the RenderObject that was
the root of the RenderView. This CL introduces a RenderViewWrapper and uses it
in a new AppContainer widget root. This change allows us to make App a
non-magical Component that is inserted into the AppContainer in the newly
introduced runApp function.

This is a completion of Eric's WIP patch:
https://codereview.chromium.org/1179663005/
Low level support for creating a paragraph that contains
runs of styled text. The styles may be nested.
The Paragraph and RenderParagraph classes have been
replaced by Inline and RenderInline. Styled text is defined
with a tree of InlineText and InlineStyle objects.

Make old users of RenderSizedBox use RenderConstrainedBox.
Change the semantics of BoxDecoration.apply* to actually apply the provided constraints to the current constraints, rather than the previous behaviour of merging them neutrally.
