CanvasFormattedText Styling Prototype

This change resurrects @sushraja's changes to add styling abilities to
CanvasFormattedText.  Note that this implements an older version of the
API, which is changing rapidly.

Original description:

Add support for styling CanvasFormattedText

This change adds a styleMap on the CanvasFormattedText and
CanvasFormattedTextRun. A subset of CSS properties are supported on the
CanvasFormattedText and a smaller subset on the CanvasFormattedTextRun.

A height parameter is added to fillFormattedText so that vertical
writing modes can be supported. The height/width passed to
fillFormattedText are used as the available space, while the
CSS height/width can be set on the CanvasFormattedText to control
height/width explicitly.

Logo Chromium

Chromium is an open-source browser project that aims to build a safer, faster, and more stable way for all users to experience the web.

The project's web site is https://www.chromium.org.

To check out the source code locally, don't use git clone! Instead, follow the instructions on how to get the code.

Documentation in the source is rooted in docs/README.md.

Learn how to Get Around the Chromium Source Code Directory Structure .

For historical reasons, there are some small top level directories. Now the guidance is that new top level directories are for product (e.g. Chrome, Android WebView, Ash). Even if these products have multiple executables, the code should be in subdirectories of the product.
