pattern_as_dict() in fontconfig.c never read FC_MATRIX, so any per-font transform set by fontconfig was silently dropped. fontconfig ships a default rule (90-synthetic.conf) that applies a slant matrix to any roman-only font when italic is requested, which is why italic CJK has been rendering upright in kitty. Read the matrix, carry it on the descriptor as a 4-tuple of doubles, apply it once in face_from_descriptor() via FT_Set_Transform, also inform HarfBuzz via hb_font_set_synthetic_slant + hb_ft_font_changed so shaping reflects the slanted rendering. Extend face_equals_descriptor() to compare the matrix so the per-FontGroup fallback cache returns the right face when upright and italic share a font file. The FT transform is sticky on the face, so subsequent FT_Load_Glyph calls inherit it with no per-call overhead, and the per-Face glyph atlas cache stays correct because the matrix is set at init and never changes. Pure shears (xx=1, yy=1) preserve horizontal advance and do not disturb monospace cell width. The HB synthetic_slant call is gated on HB_VERSION_ATLEAST(4,0,0) since setup.py allows down to 1.5.0. hb_ft_font_changed runs unconditionally to invalidate any populated caches. Refs #9857, #9700. |
