encodation in certain cases (and no pessimizations found so far),
props lyngklip (BWIPP);
fix extended char latching when exactly 3 extended chars at end;
count code set C (not digits) in loop deciding when to
shift/latch to extended for better estimate
AZTEC: return warning if ECC < 5% (due to bit-stuffing when version
given); return error if > 22 layers (Zint 26) for Reader
Initialisation symbol requested for better error message
AZTEC/HANXIN/QRCODE: consolidate different ECC data size tables
into one indexed by ECC
DBAR_EXP: check for reduced length <= 77 up front for better error
message
HANXIN: use `malloc()` rather than `z_alloca()` for large binary
array
QRCODE: `ecc_level` now 0-based (not 1-based)
MICROQR: consolidate different version end routines into one
`microqr_end()` and use new `microqr_data` table to simplify code
MICROPDF417: use table for max codewords per column
library: centralize all error messages using new `errtxt()`,
`errtxtf()`, `errtxt_adj()` funcs that protect `symbol->errtxt`
from overflow, & try to make error messages more consistent
thru-out, adding more feedback info to many, & use positional
args "%n$" in prep for l10n (maybe);
`is_sane/is_sane_lookup()` -> `not_sane/not_sane_lookup()`,
returning 1-based position (zero on failure) instead of bool;
`long` ints -> plain `int` (except those dealing with `ftell()`,
`fread()` etc) as depend on int being 32-bits already
GUI: in "grpDATF.ui" use "PlainText" rather than "RichText" for
tracker ratio examples as height of text messing up sometimes
manual: clarify Codablock-F length maximum & add examples
docs: README: pandoc 3.5, Ubuntu 24.04
CMake: use "-Wpedantic" for Clang only as GNU complains about
`errtxtf()` positional args "%n$"
CODE49: Better error message on ZINT_ERROR_TOO_LONG
manual: Use floating pt notation for floating pt args on options
backend/tools/data: Remove overlooked "GB2312.TXT" from git
raster: `size2` -> `prev_size`; one line `malloc()`s
C25/CODE128: some code fiddling
tests/PNG: Add some more text examples
from ZXing (props Alex Geller) - about 25-60% slower depending on
data & stack heavy but does improve some outcomes when FNC1s
present (GS1_MODE or manual) although not much else it appears
(the previous algorithm was very good), but has a logical clarity
the other lacked - funcs `c128_dxsmooth()` etc shared with
CODE16K now moved there and renamed as `c16k_`;
also fix extended char latching when exactly 4 extended chars
at end
also manual code set switching now honoured exactly even if
immediate shift required;
manual: make explicit that AI "(00)" and "(01)" prefixes added by
Zint are HRT-only
general: add `extern "C"` wrappers to a few header files
ticket #324, props Jim Shank;
also improve encodation for a few limited cases;
also some code fiddling
BWIPP: update to latest
raster: check for overflow on `size + size2` in `raster_malloc()`
vector: put `malloc()`s on one line for grep ease
docs: pandoc-3.3, clang-tidy-20
`iso3166list` linter and adjusting all others to allow for
multiple optional linters (by checking `data_len` vs `offset`)
library: change invalid `input_mode` reset to return warning;
split func table into 2 - func declarations without prototype
will be error in C23;
make invalid symbology check a separate function using a table
and call near beginning of `ZBarcode_Encode_Segs()`;
in `ZBarcode_BarcodeName()` save some bytes by simplifying
name table and removing "BARCODE_" prefix from entries
output: fix pack logic to use pragma by default (actually more
portable than `__attribute__`)
common.h: remove C99 detection which was artifice of specifying
"-std=", and rejig layout to be more logical
BWIPP: update to latest version
general: change `ZINT_VERSION_BUILD` tests to `#if`s
general: further fiddling with some tables to save a few bytes
CLI: change function arg `optarg` -> `arg` so doesn't shadow
global
general: library now compilable with Comp Cert C (though as it
doesn't support `alloca()` will have multiple memory leaks)

in particular)
qzint: check `__GNUC__` version for "-Wstringop-truncation"
suppression
outputting to in-memory buffer `symbol->memfile` instead of to
file `symbol->outfile`, ticket #301
Add "README.clang-tidy" and ".clang-tidy" options file
Suppress some warnings
2017 -> 2022 (2017 moved to "vs2017") and simplifying lpng
build (use "nmake" - "libpng16_static.lib" -> "libpng.lib");
update various ".sln", ".vcxproj" & "*.pro" files
update_version.php: update copyright year also in "*.rc" files
manual: note Ultracode 2023 now released but not yet supported
whjitespace at bottom of CODABLOCKF/CODE16K/CODE49 if BIND_TOP
set); add left/right fudge to guard whitespace placements so
appear closer to edge for SVG/qzint (undone by EMF/EPS)

raster: add `ZFONT_HALIGN_CENTRE/LEFT/RIGHT` flags and process
in `draw_string()` (for drawing EAN/UPC outside digits), and
for `ZFONT_HALIGN_CENTRE` round when calculating centre
(shifts some texts 1 pixel left)
raster/vector: use offsets into `symbol->text` for EAN/UPC
instead of `out_upcean_split_text()` (removed)

printed for raster with scale < 1;
move CLI HRT section up;
add one-page docs/manual.html to git - should do same for 3.1M
manual.pdf??
other: remove some no longer used backend/tools, readme-cmake
(was only set on BMP output to length of BMP pixel array)

CODE39/EXCODE39/LOGMARS: new hidden check digit option
(`option_2 = 2`)
qr.c: suppress bogus gcc-13 warning (only appears on optimize)

MSI_PLESSEY, CODABAR, DAFT, DPD, MAILMARK_2D, ITF-14, PZN,
UPNQR, CHANNEL, CODE93 and VIN, adjusting grp uis.
change Data dialog button (ellipsis) QToolButton -> QPushButton
& vice versa zap/clear/eye/swap/scale buttons QPushButton ->
QToolButton for better mac compat (also makes sense);
remove some mac hacks that no longer seem necessary;
use folder icon for Export dialog directory button
manual: document new Symbology-specific groupbox & CODE39/etc
hidden check digit option; add annexes on Qt and Tcl backends;
narrow some tables for better txt output;

default
raster/vector: rename `text_height` -> `font_height`
remove legacy "T" prefix from def commands; reinstate previous R
(TR) def so as to use I (TB) copy to save file size, & for ULTRA
pre-group rects by colour to enable use; adjust H (TH) def so
can use new J copy to save file size; various other fiddles
manual: Royal Mail Mailmark - put Destination+DPS & RTS in tables
for readability
add missing Table caption "Micro QR ECC Levels";
update README for pandoc-3.1.3;
remove TODO Windows instructions which never worked and likely
never will

enable embedding of font in vector output - currently only for
SVG output of EAN/UPC
GUI: use "OCR-B" font for EAN/UPC and "Arimo" for all others (was
"Helvetica" for both); paint background of screen preview light
grey so as contrasts with whitespace and quiet zones
