Remarks
The enum specifies the part of Hough space to calculate.
Each member specifies primarily direction of lines(horizontal or vertical)
and the direction of angle changes.
Direction of angle changes is from multiples of 90 to odd multiples of 45.
The image considered to be written top-down and left-to-right.
Angles are started from vertical line and go clockwise.
Separate quarters and halves are written in orientation they should be in full Hough space.
