reference is stored in &fbc[n].ref_crc inside the main function
test_display_mpo(). The Other MPO tests had alot of iterations so the
reference crc was saved before starting the tests. Since the setup code
is the same for this test, its using the same logic.

No particular reason for using random positions, I will take a look at
test_cursor_spots(). Thanks
