These transforms are currently very basic but they seem to mostly work.

This CL is a first pass at implementing container in fn2. In this approach,
Container is a Component that builds a number of RenderNodeWrappers depending
on what is needed.

BlockContainer uses a RenderBlock to lay out its children.

Prevously we listened for events on the document and then walked up the
component hierarchy looking for EventListenerNodes. Now we do something similar
by hooking the event dispatching logic in the AppView.

Refactor image handling in Sky to expose the loader and image as separate classes to Dart code. This makes it possible to avoid unnecessary paints, by only painting once when the image has loaded. Now that we've separated the loader and image classes, we can implement an image cache in Dart.

This reverts commit a413c8319fe9a46dc131f6efe275d014c9cb7eb9.

Reason: seems to have broken Sky tests:
Regressions: Unexpected crashes (2)
  raw/render_box.dart [ Crash ]
  raw/render_flex.dart [ Crash ]

We'll eventually turn this into a full fn2 component, but for now it's just an
example.

To make this work, I created a schedule.dart as a start to implementing
scheduler.md. For now, I've kept the API similar to the web platform so that
the old world can continue use it backed by sky.window.requestAnimationFrame.

I'm sure we'll want something more sophisticated in the near future.

Next step is to actually animate this updating layout.

This dramatically simplifies the layout model.
I haven't gone through and simplified the existing functions, we should probably go through and figure out if they can be cleaned up a bit.

This gets things off the ground barely enough to show some pixels.
These are not pixels that are actually part of the stock app, but
it's a start.

I had to add back document.createText() since new Text()
does not work in the new world yet.

LayoutRoot is a new Dart-exposed class which holds the Frame and
all associated machinery, sufficient to trigger a restyle
and layout of the subtree.

This is all kinda hacky and I'm sure likely to cause many
crashes if folks call random methods on these disconnected
trees.

But this makes it at least possible to paint text for now
and we can improve this in the coming days.

This really should have Adam's review.  It's hugely hacky
but I'd like to negotiate out with him the timeline on
which we should fix some of these hacks.

- makes the event logic not involve a boolean return value (since we ignored it anyway)
- splits the event handling logic into two steps, hit testing and event dispatch
- introduces an App class on the Dart side to factor out the interaction with the C++ side
- ports sector-layout and simple_render_tree to the new App infrastructure
- port simple_render_tree to the new event handling logic
- implement hit testing for the sector-layout demo
