Screen scraping API

[migueldeicaza]

Now that I made HeadlessTerminal public, as I need it for fuzzing, perhaps I should surface more information about the contents of the screen and make a handful of internal classes public.

APIs to surface:

Saving:

• [ ] save (to: URL, format: SaveFormat = .txt)

Accessing content"

• [ ] cols/rows
• [ ] cursorLeft/cursorTop
• [ ] scrollRegion/marginRegion
• [ ] getCell (line: Int, col: Int) -> CharData
• [ ] getText (line: Int)
• [ ] getAttributedText (line: Int) -> [CharData]

Writing to the screen, some basic operations, could surface more:

• [ ] clear ()
• [ ] setColor (...)
• [ ] setCursorPosition (...)
• [ ] write (str)
• [ ] getRegionText (...) -> [String]

Record input/output:

• [ ] setOutputRecorder (...)
• [ ] setInputRecorder (...)
