Returns
operator >(Vector2I, Vector2I)
Compares two Vector2I vectors by first checking if
the X value of the left vector is greater than
the X value of the right vector.

with the Y values of the two vectors.
This operator is useful for sorting vectors.

Whether or not the left is greater than the right.
