Clients can just register persistent frame callbacks if they want to do some
processing every frame.  Also, add some more trace events.

The fix is just to call syncFields() after calling setParent(), not
before. This way makes more sense anyway.

Also, check in some debug tools I used to track this down, and
document some of the debug tools I used.

Also, minor fixes to style.

Now we cache Paint objects for ColorFilter and Opacity, which gives Skia a
chance to retains the underlying GPU resources.

Rearrange code in widget.dart StatefulComponent to be more like the order in which it actually runs.

This will make the diff of a subsequent CL much cleaner.

Creating a new display list is having an unexpected effect on the GPU
rasterization times. This CL removes createNewDisplayList from RenderTransform
and RenderInkWell until we have a better understanding of when we want to use
it.

Added a callback to BlockViewport so that the scrollable can
stay in sync with the viewport's contents.

R=ianh@google.com

Also, fixes the stocks list to work properly including hit testing at
the bottom of the screen.

New classes:

RenderViewport: a class that supports positioning a child inside
itself and offsetting it.

Viewport: a RenderObjectWrapper that wraps RenderViewport.

ScrollableViewport: a Component that hooks Viewport up to some
scrolling behaviour.

Code changes:

RenderBlock now only works when it has an unbounded height constraint.
I removed the clipping in there since it's no longer needed.

I made FixedHeightScrollable use Viewport instead of hand-rolling its
clipping with Transform and Clip. This is what fixes the stocks list
hit testing at the bottom of the screen.

I made anywhere that used to use Block now use ScrollableViewport.

RenderFlex now takes a list of children.

Justifications for test changes:

tests/examples/stocks: changing FixedHeightScrollable to use a
RenderViewport instead of a RenderClipRect/RenderTransform combination
removes the use of an actual transform.

The scroll physics was the last client of the old frame generator. With this

To make sure this doesn't break the markNeedsLayout() logic, I added members to track who is currently painting.
Also, some minor rearrangements of the code in object.dart about painting.
Also, make exceptions in debug mode rethrow so we get a stack trace.
