ISO/IEC 15420:2009 4.3.5 (and BWIPP) and adjust righthand outside
digit to be 4X/2X instead of 5X/3X (ISO/IEC 15420:2009
Annex A.2) away from main symbol so as not to touch add-on
TODO: revisit when standard clarified
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$" in prep for l10n (maybe);
`is_sane/is_sane_lookup()` -> `not_sane/not_sane_lookup()`,
returning 1-based position (zero on failure) instead of bool;
`long` ints -> plain `int` (except those dealing with `ftell()`,
`fread()` etc) as depend on int being 32-bits already
GUI: in "grpDATF.ui" use "PlainText" rather than "RichText" for
tracker ratio examples as height of text messing up sometimes
manual: clarify Codablock-F length maximum & add examples
docs: README: pandoc 3.5, Ubuntu 24.04
CMake: use "-Wpedantic" for Clang only as GNU complains about
`errtxtf()` positional args "%n$"
Adapted from OkapiBarcode, with stricter interpretation (only pad
if "+4" totally absent), props Daniel Gredler
gs1: update to latest gs1-syntax-dictionary (linter mm -> mi)
bwipp: update to latest
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)

outputting to in-memory buffer `symbol->memfile` instead of to
file `symbol->outfile`, ticket #301
Add "README.clang-tidy" and ".clang-tidy" options file

also)
rename `ZINT_CAP_EXTENDABLE` -> `ZINT_CAP_EANUPC`
(`ZINT_CAP_EXTENDABLE` marked as legacy)
CODE128: increase no. symbol chars max 60 -> 99
EAN-2/EAN-5: fix `BARCODE_BIND_TOP/BIND/BOX` output
GS1_128: warn if data > 48 (GS1 General Specifications max)
common: `is_extendable()` -> `is_ucpean()`

EAN/UPC: fix excess 1X to right of add-ons
Composites: fix excess whitespace; fix quiet zone calcs to allow
for linear shifting
CLI: use own (Wine) version of `CommandLineToArgvW()` to avoid
loading "shell32.dll"
Move "font.h" -> "raster_font.h"
EPS/SVG: use new `out_putsf()` func to output floats, avoiding
trailing zeroes & locale dependency
EPS: simplify "TR" formula
SVG: change font from "Helvetica, sans serif" to "OCR-B, monospace";
use single "<path>" instead of multiple "<rect>"s to draw boxes
(reduces file size)
Add `EMBED_VECTOR_FONT` to `output_options` (CLI `--embedfont`) to
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
EMF: prefix funcs with `emf_`; simplify string `halign` handling
large: rename `large_int` -> `large_uint`
CODE128/common: move `c128_hrt_cpy_iso8859_1()` to
