TODO

Main things to do:

* Clean up parsing code, make a nice library out of it for parsing ansi codes and terminal output for any application.
** It would be nice to have a single library that goes both ways -- both parse and generate ansi codes.
* figure out a good interface for the actual terminal object, make a public library for creating terminals (with whatever interface you want to layer on top)
* improve the terminal canvas, give it a good stable public interface
* make a fast xterm.  Currently it's too slow to use as a daily-driver terminal (all due to the display speed).
* add scrollback
* generally clean things up
* make a tmux/screen style terminal multiplexer.
* change the underlying data structures to allow NON-infinite history.
* make something non-terrible for key binding/interpretation
* add some way to configure things
* add documentation as more public parts are released
