Editor

This is an experimental Editor layer that abstracts out SkShaper text layeout for easy embedding into an application. The Editor layer is agnostic about the operating system.

+--------------------------------+
|Application                     |
+-+----+-------------------------+
  |    |
  |    |
  |  +-v-------------------------+
  |  |Editor                     |
  |  +-+----+--------------------+

The Application layer must interact with the:

Windowing system
File system
Clipboard
Keyboard/mouse input.

Try it out:

tools/git-sync-deps
bin/gn gen out/default
ninja -C out/default editor

out/default/editor resources/text/english.txt

cat resources/text/*.txt > example.txt
