Documentation
The layout is the same as samp(bw)samp, but alternating gray and white lines.
There are two macros defining the behavior:
samp(pro.matrix.cycle)samp defines the length of the cycle (number of white
and gray lines). It defaults to 6.
samp(pro.matrix.gray)samp defines the number of gray lines. Default is 3.
