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$" in prep for l10n (maybe);
`is_sane/is_sane_lookup()` -> `not_sane/not_sane_lookup()`,
returning 1-based position (zero on failure) instead of bool;
`long` ints -> plain `int` (except those dealing with `ftell()`,
`fread()` etc) as depend on int being 32-bits already
GUI: in "grpDATF.ui" use "PlainText" rather than "RichText" for
tracker ratio examples as height of text messing up sometimes
manual: clarify Codablock-F length maximum & add examples
docs: README: pandoc 3.5, Ubuntu 24.04
CMake: use "-Wpedantic" for Clang only as GNU complains about
`errtxtf()` positional args "%n$"
`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)

table; warning suppression "-Wpedantic" -> "-Wstrict-prototypes"
GRIDMATRIX/HANXIN/QRCODE: `xx_define_mode()`: multi-dim `char_modes`
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
`qr_in_numeric()`/`hx_in_numeric()` (restrict to 3, not 4),
ticket #300 (#16), props Andre Maute
manual: "Maxicode" -> "MaxiCode"; add max capacities for matrix
barcodes
GS1 percents in `qr_in_alpha()`, ticket #300, props Andre Maute;
also defensively re-calc version 40 mode to prevent possible
further crashes

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)
BMP/EMF/GIF/PCX/PNG/PS/SVG/TIF: use new `out_colour_get_rgb()`
routine (replaces `colour_to_XXX()`)
general: simplify/fix some `error_number` handling/returning
frontend: truncate overlong `--primary` instead of ignoring;
negative floating pt option (for `--textgap`)
man page: list size detail for matrix symbols (`--vers`)
manual: further fiddling with scaling text; some typos
(was only set on BMP output to length of BMP pixel array)
EXCODE39: change to display check digit in HRT by default
CODE39/EXCODE39/LOGMARS: new hidden check digit option
(`option_2 = 2`)
qr.c: suppress bogus gcc-13 warning (only appears on optimize)
GUI: move some symbology-specific options into Data Tab so
separate tab unnecessary (those with few options and no
Composite/ECI), namely: all C25XXX, CODE39/EXCODE39/LOGMARS,
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

various other fiddlings
`EANUPC_GUARD_WHITESPACE`, CLI `--guardwhitespace`) (ticket #287)

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

(though probably never reached); use "[tp++]" throughout
Add const to static tables missing it and also to some variables
Change "debug" -> "debug_print" throughout
- use fixed-length string tables (mostly) instead of (char *) pointer ones
(saves ~40K)
- re-use C128Table for CODABLOCKF and CODE16K
(required removal of Stop character and extra CODE16K-only entry)

- replace last remaining bin_append()s with bin_append_posn();
bin_append() removed
- add length arg to toupper() and expand() (avoids strlen())

prefix defines (SHIFTA -> C128_SHIFTA etc) and existing exported routines
- use factor XOR toggle trick in checksum calcs (avoids branch)
- raster.c: fill out single 1-pixel row and copy using new draw_bar_line(),
copy_bar_line() routines; similarly in buffer_plot compare previous line &
copy if same (same technique as used to improve non-half-integer scaling,
significant performance increase, (c) codemonkey82);
also done for PNG (BMP/GIF/PCX/TIFF not done)
- raster/vector/output.c: shorten "output_" prefix -> "out_";
sync vector to other raster changes to try to keep source files similar
