`EANUPC_GUARD_WHITESPACE`, CLI `--guardwhitespace`) (ticket #287) EAN-2/EAN-5: HRT now at top instead of at bottom for standalones, following BWIPP CLI: batch mode: don't close input if stdin 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 `hrt_cpy_iso8859_1()` and add `ZINT_WARN_HRT_TRUNCATED` warning (for future use) Various symbologies: replace `printf()` with `fputs()` (symbol->debug) QRCODE: better assert(), removing a NOLINT (2 left) CLI: add some more barcode synonyms for DBAR common: various fiddlings CMake: don't include png.c unless ZINT_USE_PNG (avoids clang warning)
