fields `raw_segs` and `raw_seg_count` instead of `text`, and to
do so for all symbologies, using new common funcs `rt_cpy()` etc.
MICROPDF417: return ECC percentage in top byte of `option_1`
DBAR_EXP_STK: return `option_2`/`option_3` feedback
CLI: change warning text "ignoring" -> "**IGNORED**"
GUI: show feedback for DBAR_EXP_STK, MICROPDF417, UPNQR
ctest: fix recent inability to run tests via "ctest" on Windows
(MSVC) by using cmake 3.22 feature `ENVIRONMENT_MODIFICATION`
manual: document feedback and RAW_TEXT in new "Feedback" section;
rephrase some symbology descriptions
test suite: new general-use arg "-a"; add `func_name` to context;
new "test_bwipp" test for testing BWIPP against ZXing-C++
DOTCODE/GRIDMATRIX/HANXIN/MICROPDF417/MICROQR/PDF417/QRCODE/
RMQR/ULTRA: set `option_1/2/3` to values used in encodation
("Feedback options"), and add new access methods
`encodedOption1()` etc. to Qt Backend, and use in GUI to provide
better feedback on "Automatic" selections
- AZTEC: give more precise warnings in low ECC situations, and
indicate via `option_1` by setting to -1 (min 3 words), 0
(<5% + 3 words) (`ecc_ratio`)
- set_height: fix non-compliance false positives by using epsilon
in checks (prompted by CODABLOCKF non-compliant warning for
zint-generated compliant height - floating point `rows` mult !=
`zero_count` div; one test regression for CODE93);
better warning messages on non-compliant heights (min/max)
- manual/man page: fix DATAMATRIX Sizes tables "28 12x26" ->
"27 12x26"
- GUI: AZTEC/CODEONE: add Zint versions to comboboxes
- DOTCODE: improve error messages re size too small/large
- ULTRA: better ZINT_TEST codeword dump (ZINT_DEBUG_TEST)
- general: various tabs -> spaces; prettify main .rc files;
trailing spaces; small amount of code fiddling (CODE16K)
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
Rename barcode funcs to same as BARCODE_XXX name
library: barcode funcs array for dispatch, used for ZBarcode_ValidID() also
general: change is_sane() comparison to nonzero from ZINT_ERROR_INVALID_OPTION
MAILMARK: fuller error messages
CODABAR: add option to show check character in HRT
zint.h: use 0xNNNN for OR-able defines
GUI: add guard descent height reset button, add Zint version to window title,
static get_zint_version() method, use QStringLiteral (QSL shorthand),
use SIGNAL(toggled()), add errtxt "popup" and status bar, add icons,
add saveAs shortcut, add main menu, context menus and actions, add help,
reset_view() -> reset_colours(), add copy to clipboard as EMF/GIF/PNG/TIF,
lessen triggering of update_preview(), shorten names of getters/setters,
simplify/shorten some update_preview() logic in switch,
CODEONE disable structapp for Version S
qzint.cpp: add on_errored signal, add missing getters, add test
GRIDMATRIX, MAXICODE, MICROPDF417, PDF417, QRCODE, ULTRA
DOTCODE: use pre-calculated generator poly coeffs in Reed-Solomon for
performance improvement
PDF417/MICROPDF417: use common routine pdf417_initial()
GUI: code lines <= 118, shorthand widget_obj(),
shorten calling upcean_addon_gap(), upcean_guard_descent()
various backend: var name debug -> debug_print
