> The functionality should not be affected. Instead of passing 2 numbers (1 for # of preceding
rows and 1 for # of following rows), we will pass WindowFrameDef object around. In the following
subtasks, it will be used to support additional window like {{rows between x preceding and
y preceding}} and {{rows between x following and y following}}.
