We were hitting an assert in RenderCustomPaint that the callback wasn't null.

Export Point, Size, Rect, Color, Paint, Path, BoxDecoration, Border, BorderSide, EdgeDims, and FlexDirection from fn2.dart
That way most of our libraries don't have to use sky.Foo all over the place, and we can reduce the number of imports in most Dart components.

 - several places where we use a getter knowing that it will return a
   subclass of its declared type, even asserting that it does, but
   where the analyzer is worried that the getter might start returning
   a new value unexpectedly, solved by having a temporary local
   variable shadow the getter and asserting that it doesn't change
   value
 - many many places where we do this with parentData specifically,
   solved by type-erasing parentData.
 - a place where a mixin wants to be subclassing another class, and
   uses its methods, solved by saying that the mixin is abstract but
   implements the superclass

Turns out Scaffold needs to hook _remove, so we need to rename it to remove to
expose it outside fn2.dart.

Fixed the mojo deploy script to no longer deploy mojo.
mojo now uses a more sophisticated CDN, etc.

Fixed old fn.dart to work again. :)  Looks like it was
victim of a mass rename.

Fixed engine.cc to be able to handle navigating from
WebView content to SkyView content.  We can't handle
the other direction yet, but we don't need to.
/sky_home is written in the .sky system but all of our
new examples are .dart (and thus SkyView).

Rename "BorderSide.None" to "BorderSide.none", since it's a constant, and change the sky.Size.infinite() constructor to a constant.

This CL does a bunch of ground work for getting StockList ready for use in

We should be asserting that old.root is a ContainerRenderObjectMixin because
we're able to manipulate its child list.

This makes debugging the render tree a lot easier. Just print the node
you care about, and you get an indented tree view of its subtree,
including settings. New subclasses should implement the new virtual
method debugDescribeSettings() to expose new settings.

This CL makes FixedHeightScrollable able to measure heights. In the DOM-based
version, FixedHeightScrollable forced a synchronous layout in a microtask in
order to measure the size of itself and its children. In the DOM-less version,
we now require the subclass to tell us the item height and we measure our own
height using a layout callback.

The root cause of the crash was threefold:
 - you can't enumerate enums, in dart; you have to enumerate their values.
 - RenderNodeWrapper was trying to call remove(child.root) on its root, but that's
   not something that all RenderNodes have
 - when a RenderNode was deparented, its relayoutSubtreeRoot wasn't removed, so
   the node ended up in an inconsistent state regarding its parent tree
