We used to share memory between Dart strings and WTF::String objects by
way of the Dart externalized strings. That used to be important when the
DOM shared many strings between C++ and Dart. However, now that we don't
retain strings in C++ much anymore, we don't need this complexity.
This patch removes DartStringCache and the integration. It also unwinds
several cases where we were converting back and forth between
WTF::String and std::string for no reason. Now we use std::string more
consistently.
For the case of ParagraphBuilder::addText, we now take a raw const
char*, which more closely matches the API the DartVM exposes. That means
we do a single copy out of the VM and into the render tree at that
point.
Moving the microtask queue into tonic solves three problems:
1) Removes three levels of indirection when invoking microtask
callbacks.
2) Removes the sky/engine/dom directory entirely.
3) Removes the last client of the (inefficient) DartValue class.
The motivation of this CL is enhance the font fallback score design
to support multiple language font fallback.
This CL contains following changes:
- Break language based font score into two: script-based score and
primary-language-based score.
- The primary-language-based score is 0 if the script-based score is 0.
If the script-based score is not 0 and the primary language is the
as same as the requested one, the font gets an extra score of 1.
- The language score gets a higher multiplier for languages higher in
the locale list.

Tailor grapheme boundaries so sequence emoji are one grapheme - DO NOT MERGE
Make it so it's not possible to position the cursor inside an emoji
formed by a sequence including zero-width joiners.

The matrix argument to drawPicture doesn't seem to do what we want exactly.
Instead, use the normal matrix in the canvas. Also, handle cull rects with
non-zero left and top coordinates.
Fixes#1229
Now we just depend on Skia and Base, which makes the compositor easier
to understand.
Also, update our skia/ext/refptr.h to match the current version of the
code in Chromium. This version adds support for several useful C++11
patterns.
