This returns us to a more stocks1-like arrow style.
Also it uses math rather than transforms to rotate the arrow, since transforms are expensive.
It also removes the save/restore calls, which are _really_ expensive.

Also some minor style fixes.

Short-circuit the relayoutSubtreeRoot when the child couldn't change dimensions anyway because the parent constrained it.

The relayout subtree root concept is intended to handle the case where
a node, when it lays itself out for a second time, changes its opinion
about what dimensions it should be. In such a situation, the parent,
if it based its own opinion about what size _it_ should be on the
child's dimensions, would also need to lay itself out again. Thus,
when this scenario is possible, the child remembers the parent, and
when it would be told to relayout, we actually start the layout with
the parent.

In practice, this chains, and we end up with nodes that point to
ancestors ten or more steps up the tree such that when the inner most
child re-lays-out, the whole app ends up relaying out.

This patch tries to short-circuit this for the case where the
constraints being applied to the child are such that actually, the
child has no choice about its dimensions. In that case, the parent
can't change dimensions when the child re-lays-out.

This makes a huge difference on the stocks demo app. Without this, on
the third rendered frame, there are 72 relayoutSubtreeRoot links, the
deepest chain is 8 deep, and 9 of the chains are only 1 level deep.
With it, there are 63 relayoutSubtreeRoot links, the deepest chain is
only 4 deep, and 38 of the chains are only 1 level deep.

Previously, the wavy underline code only knew how to draw a complete
period.

This change adds the ability to draw a partial period of the wave.

Previously, the code tried, but failed, for reasons I cannot
determine, to fit the width of the inline by extending the period to
be an integral factor of the width.

This is bad because as you type text, the underline wave of earlier
characters would jiggle.

This fixes that by not changing the period of the wave when the length changes.

It's interesting to compare this to the previous code. Here's a test
that shows this in Safari/Chrome:

   http://software.hixie.ch/utilities/js/live-dom-viewer/?saved=3543

Notice how as you type "i"s, the underline changes how far it extends
(obviously a bug) but also what the period of the wave is (which looks
especially ugly when typing).

Firefox, on the other hand, renders something that isn't actually a
wave; it's a saw-tooth pattern with straight lines between each
direction change. This works for small font sizes at low densities,
but is not great on modern screens.

This CL addresses this issue by computing the bezier curve control
points for the curve that consists of just the remaining fraction of
the period. To do this, however, it allocates an object and solves a
bezier for x (which includes a numerical integration), which is
certainly a performance concern. Apps that try to wavy-underline an
entire UI are going to maybe suffer. Since this is typically going to
be used for spelling checkers, it means people who spell better will
have better performance.

(I haven't tested this to see what the perf impact actually is. If
it's actually bad, we can probably cache the results of the
integration pretty trivially.)

Update sky_server:
 - update its help string to admit that it wants the package path as well.
 - be quiet by default, since it makes the build chatty.
 - have a -v for verbose mode, for people who like it chatty.
 - have a default port of 8000, since that's what everyone used.
 - have a -p option to set the port, for people who don't use the default.
 - remove its mapping for gen/, since a TODO told me to.
 - remove the dependency on the build configuration, since it's no longer used.
 - teach it about .dart files.
 - rename sky_server/README to README.md, for consistency with other READMEs.
Update shelldb to speak the new sky_server protocol.
Update tests/services/iframe-embed-vmc.sky since the sky_server change broke the hack it was using.
Update skyserver.py to speak the new sky_server protocol.
Make webkitpy use SkyServer instead of spawning sky_server itself, since a TODO told me to.
Teach webkitpy about dart files.
Teach test_perf about dart files. (untested)
Teach sky_tool about main.dart, main.sky is deprecated. (untested)

Turn on wavy underlines. The waves aren't very pretty yet (they are too short somehow), I'll fix that in a subsequent CL.

I abstracted out the wavy underline code so that it doesn't duplicate the code for horizontal and vertical lines.

We're now 25% faster as scrolling the infinite list than stocks1.

This CL makes cleans up some code to avoid calling layout on all the rows in

Ok, not really zero. Actually 72 if you include warnings from non-sky packages and if you include bogus warnings that can be filtered out.

If you pipe the analyzer's output through the following perl script, though, you get zero warnings on the stock app with this patch:

Currently you lose your scroll and drawer state when coming back from the settings pane.
I think we should solve this by having the Navigator maintain a Stack and
keeping the StockHome alive underneath it. But this is good enough for a first iteration.
