- Add text_gap option to allow adjustment of vertical gap between

barcode and text
- EMF/EPS/SVG/GUI: ignore BOLD_TEXT for EAN/UPC
- DAFT: up max to 250 chars
- EMF/EPS/SVG: fix addon bars placement/length when text hidden
- Qt backend: use `QFontMetrics::horizontalAdvance()` rather than
  `boundingRect()` to calc text width (seems to be more accurate)
- library: make printf/sprintf() format arg always literal string
- output: fix errtxt nos clash;
  use array for `out_upcean_split_text()` text parts
- raster/vector: smallify addon text printing logic
- frontend: warn if output file and direct options both given;
  add TODO note about `CommandLineToArgvW()` loading shell32.dll
- manual: put HRT options in own section
