• `<<`: Are the X values of the first bounding box strictly less than those of the second one?

• `>>`: Are the X values of the first bounding box strictly greater than those of the second one?

• `&<`: Are the X values of the first bounding box not greater than those of the second one?

• `&>`: Are the X values of the first bounding box not less than those of the second one?

• `<<`: Are the X values of the first bounding box strictly to the left of those of the second one?

• `>>`: Are the X values of the first bounding box strictly to the right of those of the second one?

• `&<`: Are the X values of the first bounding box not to the right of those of the second one?

• `&>`: Are the X values of the first bounding box not to the left of those of the second one?

• `<<|`: Are the Y values of the first bounding box strictly below of those of the second one?
