401 3168 blocks per field. Each pixel consist of two bytes; 128 bytes per block;
402 1024 bits per block. 100% in the new driver mean 1:2 compression; the maximum
403 output becomes 512 bits per block. Actually 510, but 512 is simpler to use
406 Let's say that we specify d1q50. We thus want 256 bits per block; times 3168
407 becomes 811008 bits; 101376 bytes per field. We're talking raw bits and bytes
408 here, so we don't need to do any fancy corrections for bits-per-pixel or such
