The popup menu in the stocks app is supposed to size its width to the max
intrinsic width of the menu. This CL teaches it how to do that.

It's a shame that we need to ceilToDouble the output of RenderParagraph. If we
don't do that, we run into floating point layout trouble and the menu triggers
a line break. The correct fix is to do layout in fixed point.

I don't think this is the final API we're going to use.

I suspect we'll add a TextStyle struct to hold
color and size, etc. which back-ends into CSS like
this does today.

Currently no one uses this color even though it exists.

This is one step towards fixing:

This CL splits getIntrinsicDimensions into getMinIntrinsicWidth,
getMaxIntrinsicWidth, getMinIntrinsicHeight, and getMaxIntrinsicHeight so that
we can properly shrink-wrap the stocks app menu. This CL just contains the
refactoring. The use in stocks app will come in a later CL.

Also change SizedBox.

This makes the code that uses Container() and SizedBox() much more readable.

The underlying RenderSizedBox is not affected by this change.

Rather than appending the custom Foo.dart code to the end of the generated
interface, we now copy it to a CustomFoo.dart file in the output directory.
This allows us to declare it as a proper dependency.

The popup menu is displayed in the wrong location with the wrong width, but it
does draw. I've also removed the checkbox because the flex container was
causing me trouble.  I'll add it back in a later CL.

This is just another hack on top of the hack that is LayoutRoot.

We will want to untangle Document ownership further as we
iterate on LayoutRoot.  For now LayoutRoot is both very
inefficient (allocates a new Frame for each one!) as well
as crashy like this (by not actually owning the document
but rather grabbing it off the "rootElement" assigned to it).

This at least fixes this common crasher for now.

This CL is the first step towards getting PopupMenuItem working in fn2. We
introduce the ability to add a minWidth to a Container by creating a
RenderConstrainedBox class to apply the new constraints.

This includes making SizedBox default to infinite size, and making
Container default to containing one infinite-sized SizedBox. That way,
you can use an empty Container as a spacer in a flex box.

The rendering doesn't quite work, because of a bug in flex whereby it
doesn't shrink-wrap its contents in the cross-direction, it fills the
parent. Collin is on that.

I had to complicate the IDL bindings generation to allow passing an array of
colors. Without these changes, we'd try to convert the dart object to
Vector<SkColor>, which C++ thinks is Vector<unsigned>, and we'd use the wrong
converter. So I added some template grease to force it to use a
Vector<CanvasColor> converter.

Changes:
- Remove all the old tracing logic since that was a lot of code for
  just random printf debugging and nobody seems to use it
- Convert "defunct", a permanent state transition, to "mounted", a
  state that can be entered and exitted arbitrarily
- Coallesce mount/unmount notifications so there's only one per frame
- Remove handleRemoved() since we don't use it
- Rename a local variable 'parent' to 'ancestor' to avoid shadowing
  the field
- Replace uses of forEach() with for-in

Effects:
- Reusing a node provided to a constructor in a new place in a tree
  (especially at a different depth) no longer fails (it used to fail
  because the node would be marked defunct then remounted later, at
  which point it would fail)

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

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).
