[GDI32][LPK] BiDi support for ExtTextOut and GetCharacterPlacement (#534)
Introduce BiDi (bi-directional text) support for ExtTextOut and GetCharacterPlacement,
using Wine's GDI BIDI_Reorder function.
Solves the main issue with CORE-7003.
To be compatible with Win2k3+, introduce the "Language Pack" (LPK) dll.
- All the bidi code is removed from gdi32 and replaced by calls to LPK.
Gdi32 uses dynamic linking to lpk.dll. In case of linking failure no bidi processing
will be available.
- Implemented LpkGetCharacterPlacement.
- Implement LpkExtTextOut.
- Add a demo test program to show how the apis should function.
- Added all the remaining code, added special case for lpDx calculation if also
GCP_GLYPHSHAPE flag was called.
Applications that call GCP that use GCP_GLYPHSHAPE flags should also use the
GCP_REORDER flag.
(As written in
https://msdn.microsoft.com/en-us/library/windows/desktop/dd144860(v=vs.85).… )
- Add ETO_RTLREADING flag handling.
Imported the ETO_RTLREADING flag handling from wine, which changes the string part
order (runs).
A RRR1LLLRRR2 string without will show as RRR1LLLRRR2 without it, with it
RRR2LLLRRR1.
