list of all valid alignment pattern center modules under VERSION
convert bstream into codewords, as coefficients of the terms of a polynomial
2X4 module block for a regular symbol character. Regard the interleaved codeword sequence as a single bit stream, which is placed in the two module wide columns, alternately in the right and left modules, moving upwards or downwards according to DIRECTION, skipping function patterns, changing DIRECTION at the top or bottom of the symbol. The only exception is that no block should ever overlap the vertical timing pattern.

make a raw matrix according to VERSION
make a raw matrix with MODULES * MODULES elements
do not evaluate, just go ahead and mask MATRIX using MASK-IND mask pattern
minimum version that can hold NBYTES data words, or INIT-VERSION if bigger
put CUR-BYTE into MODE, and then look at following BYTES for new segment
(number of units that matches MODE, and mode for the first unmatched unit)
Paint one alignment pattern centered at (X, Y)
Paint one finder pattern starting from upleft (X, Y)
add pad codewords (after adding padding-bits) to fill data codeword capacity
add padding bits so that BSTREAM ends at a codeword boundary
