enableLigatures property
Whether glyph-merging font features are enabled.
This only permits the font to produce ligature glyphs; the painter still decides where merging is safe. A ligature is drawn only when its advance matches the cells it covers, so the cell grid never shifts. Enabling this has no visible effect unless the resolved font actually ships the features, which none of the default fallback families do.
Implementation
final bool enableLigatures;
