* `edit.draw(state, fg, hide_cursor)` -- call this from `on.draw` to display
the current editor state on the app window as requested in the call to
`edit.initialize_state` that created `state`. `fg` is the color for
foreground text (`Text_color` is a good default). Set `hide_cursor` to stop
showing a blinking cursor (usually because you want a `readonly` editor; see
below).
* `edit.draw(state, fg, hide_cursor, show_line_numbers)` -- call this from
`on.draw` to display the current editor state on the app window as requested
in the call to `edit.initialize_state` that created `state`. `fg` is the
color for foreground text (`Text_color` is a good default). Set
`hide_cursor` to stop showing a blinking cursor (usually because you want a
`readonly` editor; see below), and `show_line_numbers` to render line
numbers to the left of the editor.
