setWindowSize method
Implementation
void setWindowSize(Size size) {
final int row = size.height ~/ theme!.characterHeight!;
// 列数
final int column = size.width ~/ theme!.characterWidth!;
this.row = row;
this.column = column;
// log('setPtyWindowSize $size row:$row column:$column');
currentBuffer!.setViewPoint(row);
//也就是说如果终端有10列,这10列都能显示东西,但是 `stty size` 命令拿到的列应该是 9
