10747d6385 CODE128: Add new extra escape \^1 for manual insertion of FNC1s,
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

323b34502b zint.h: increase symbol->text size 160 -> 200;
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()`
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

6f7cdd660c - Add special symbology-specific escape sequences (Code 128 only)
for manual Code Set switching via `input_mode` flag
  `EXTRA_ESCAPE_MODE` (CLI `--extraesc`) (ticket #204)
- GUI: disable "Reset" colour if default; add "Unset" to Printing
  Scale dialog (allows unsetting of X-dim/resolution settings
  without having to zap)
- library: guard against out-of-bounds rows (negative)
- test suite: fix some clang-tidy warnings; slight coverage
  improvements

e1522e0808 backend: non-functional code-fiddling: format codablock.c (clang-format
+ manual); add SPDX to all files; prefix include guards with Z_;
  move vim comment to bottom; remove some trailing spaces

fab7435fac Performance improvements for linear encoding and raster output
- 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)
 - use pointer to destination and copy (memcpy/strcpy(), bin_append_posn())
   instead of concatenating (strcat()) (mostly)
 - replace last remaining bin_append()s with bin_append_posn();
   bin_append() removed
 - add length arg to toupper() and expand() (avoids strlen())
 - change is_sane() to use table-based flags (avoids an iteration)
 - rename lookup() to is_sane_lookup() and change to check and return posns
   and use in pointer to destination loops (avoids strcat()s)
 - remove special case PHARMA in expand() (dealt with in pharma())
 - make #define SILVER/CALCIUM/TECHNETIUM/KRSET etc static strings
 - replace strchr() -> posn()
 - CODE128: populate destination once in checksum loop; re-use and export
   some more routines (c128_set_a/b/c(), c128_put_in_set()) for sharing;
   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
 - 2of5.c: prefix "c25_"
JAPANPOST: return error if input data truncated (backward incompatible)
DAFT: max chars 50 -> 100
common.c: istwodigit() -> is_twodigit()
common.c/emf.c/output.c: use some further stripf()s (MSVC6 float variations)
library.c: new check_output_args() helper
zint.h: add BARCODE_LAST marker and use in library.c
QRCODE: remove a NOLINT (requires clang-tidy-13), one remaining
CMake: separate no-optimize from ZINT_DEBUG into new ZINT_NOOPT option

eb6e5daa2d raster.c: need ceilf(large_bar_height * si) to avoid zero height rows;
also improve non-half-int interpolation performance
raster/vector.c: use new stripf() func in "common.c" to workaround gcc
  32-bit float calculation variations
gs1.c: allow dummy AI "[]" if GS1NOCHECK_MODE and has data (#204);
  also add note re TPX AI 235 and terminating FNC1
Remove trailing whitespace in various files
