line should be cleared.
`wrap` is a boolean indicating that this line wraps to the next row.
When redrawing a line which wraps to the next row, Nvim will emit a
`grid_line` event covering the last column of the line with `wrap` set
to true, followed immediately by a `grid_line` event starting at the
first column of the next row.
