- PDF417/MICROPDF417: use latch not ps shift for padding when
spanning Text segments to avoid affecting 1st char of 2nd segment - PDF417/MICROPDF417: add optimized encoding, FAST_MODE for previous scheme; formatting changes - common.c/h: add `cnt_digits()`, comments in include and make more consistent, minor code fiddling - DOTCODE: replace `dc_n_digits()` with new `cnt_digits()` - test_qr: fix `test_qr_perf()` - composite: minor code fiddling - library: debug dump HIBC-processed input - BWIPP: update to latest
