GUI: fix chkGS1Strict enabling on startup regression from previous
commit; update CLI equivalence with --gs1strict & adjust for
implied --gs1; add tests
CMake: allow lpng/zlib and gs1encoders to take paths (for Windows)
win32/README: simplify locating lpng/zlib/gs1encoders for cmake
using above; add note on 64-bit build
manual/man page: adjust for various above changes
to get working using nmake "makefile.vcwin32", added to fork at
https://github.com/gitlost/gs1-syntax-engine;
small updates to Linux, macOS READMEs
GUI: change "chkGS1Strict" to be hidden instead of manually adding
pandoc: latest version
`DATA_MODE`); allows ZXing-C++ to be built in writer-only mode
without needing "libzueci"
library: in GS1 mode check that ECI if any is ASCII compatible
general: some code fiddling, `mode` -> `modes`
filemem: remove NOLINTS (clang-tidy-20 bug fixed)
QRCODE: eliminate NOLINTs using some more asserts (clang-tidy-20);
some "de-branching" of loops
general: various code fiddlings, in particular lessen no. of
redundant parenthesized expressions, especially in conditionals,
which reduce rather than aid readibility IMNSHO
manual: mention "--dump" option
those in "backend/common.h", which are prefixed by `z_` - makes
symbol clashes more unlikely when zint is statically linked
(ticket #337, props Ulrich Becker)
DOTCODE: fix padding allowance (10 -> 52 - probable max 35) to
cover cases with large no. of columns requested and little data,
to prevent `codeword_array` buffer overflow
AZTEC/CODEONE: some code fiddling
general_field: prefix defines with `GF_`, shorten static funcs
prefix `general_field_` -> `gf_`
DBAR_OMN/LTD/EXP: add helpers `dbar_xxx_group()` to calc groups;
`dbar_widths()` -> dbar_getWidths()` & make `noNarrow` boolean;
new helper `dbar_widths()` interleaves;
various other refactorings, fiddlings etc.
DBAR_EXP: `dbar_date()` -> `dbar_exp_date()`
upcean: make `cc_rows` const
in `ESCAPE_MODE`
composite: empty primary now returns `ZINT_ERROR_INVALID_DATA`
rather than `ZINT_ERROR_INVALID_OPTION`;
check that primary NUL-terminated
library: check that `outfile` NUL-terminated
gs1: preface all routines and linters with "gs1_"
general: some code fiddling
