- Fix crash in PATH_ExtTextOut. See bug 6587.
- Sync Information:
  Huw Davies <huw@codeweavers.com> : Add support for ETO_PDY and improve world transform support.
  Massimo Del Fedele <max@veneto.com> : Fix PATH_add_outline when mapping mode != MM_TEXT. PATH_ExtTextOut remove incorrect shift to DC origin. Correctly handle space char on Path_ExtTextOut().
  Dmitry Timoshkov <dmitry@codeweavers.com> : The MAT2 parameter of GetGlyphOutline is mandatory.
