 The generator works according to the following algorithm:
 1) **None of the levels** of the generated image **change** the pattern;
 2) The gap is a rectangle of spaces, the dimensions
    of which are equal to the width and height of the initial pattern;
 3) In every **odd level**, the gap should be in **even** positions,
