This CL replaces the (non-working) components2 InkWell with some code based on
the ink_well example. There are at least two issues with the implementation:

1) The ink splash always starts at the center of the well because we don't have
   a facility for converting from global to local coordinates, which means we
   can't tell where the tap occurred in the local coordinates we need to use
   for painting.

2) When used inside a MenuItem, the in splash disappears shortly after
   starting, presumably because the button starts highlighting, which causes a
   component rebuild and somehow we lose the RenderInkWell instance.

I plan to address these issues in subsequent CLs.

StockRows are now a relatively simple application of flex layout.

The up/down arrows are now rendered within a circle, like
the original version. The arrows are a little bigger,
because.

This would cause them to forget what the most recent child they'd been given was, with disastrous effects later.

We already know how to talk to the network_service from Dart
via fetch.dart.  Might as well use that for Image loading
as well insetad of having ImageLoader do it.

As part of this I've renamed *ImageLoader to *ImageDecoder
and moved all the image loading logic into Dart.  This required
me to teach the idl system about mojo handles so that I could
pass the resulting MojoHandle from fetch.dart up through to
ImageDecoder.

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.

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 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.
