/*
after I added DC subtraction before DCT I got 9-bit (allthough not likely to go out of 8bit range) signed data.
also increased transpose memory to 9 bits (anyway it is 16-bit wide) - see if it will help to prevent saturation
without significant increase in gates
Saturatuion is still visible on real pictures, but there was a bug - addsub<i>a_comp, addsub<i>b_comp where not using their
MSB. I added 1 more bit to add_sub<i>a and add_sub<i>b and fixed that bug. Only 2 mofre slices were used
