(EQ 17)
A value of 1 is used for x_odd_inc and y_odd_inc when no pixel subsampling is indi-
cated. In this case, the sensor is incrementing x and y addresses by 1 + 1 so that it reads
consecutive pixel and row pairs. To implement a 2x skip in the x direction, the x_odd_inc
is set to 3 so that the x address increment is 1+3, meaning that sensor will skip every
other Gr-R pair.
