)

* Re-architecture LineEditor's internal state and rendering

* Fix test related to LineEditor re-architecture

* Fix use of `@cursor_y`

Fix bug updating `@cursor_y`. Do not use `@cursor_y` while updating dialog because it is not current cursor position but cursor position at last rendered time.

* Remove useless instance_variable_set in test

These instance variables are already removed from LineEditor

* Always initialize instance variables to avoid ruby 2.7 warning, remove unused instance variable

* Call update_dialogs from reline.rb before first render

* Combine state representing rendered screen information into `@rendered_screen`

* Rename editor_cursor_ to wrapped_cursor

It represents cursor position of word wrapped whole content

* Remove unused code, tweak, add comment
