zint/backend_qt/qzint.cpp
gitlost e30e1f9651 RMQR: update to ISO/IEC 23941:2022 - R13x77 numeric cclens change 8 -> 7 
QRCODE: use stricter interpretation of ZINT_FULL_MULTIBYTE, excluding
  certain trailing bytes
libzint: fix some confusing error messages introduced by segment stuff
general: new escape chars \U, \d and \o
backend_qt: fudge rendering of border rectangles due to scaling/translation
  rounding errors TODO: better fudge
GUI: foreground/background colours -> text boxes and icon buttons, add swap
  button, independently movable picker (NULL parent), preview colour changes,
  preview Data Window changes, add clear data (del) buttons, add zap button
  and Factory Reset menu option, various other fixes
libzint: remove STATIC_UNLESS_ZINT_TEST, use wrappers
CMake: add find package QtSvg, remove QtXml
manual: split symbology and general specs and sort, move DAFT to 4-state,
  UPC/EAN -> EAN/UPC, DataBar -> GS1 DataBar always, expand MAILMARK info,
  various other fiddlings
man page: options or -> |, expand MSI Plessey check digit options
README.linux: add packages info
license: add SPDX-License-Identifier to touched files
