[LPK] Changes (#622).

Browse source 
- Changed how the ScriptIsComplex check is made to account direction, most noticeble on dxdiag,
  https://docs.microsoft.com/en-us/windows/desktop/api/usp10/nf-usp10-scriptiscomplex
  However commented out the ScriptIsComplex flag change because of a bug.

- Added a check and debug print if BIDI_Reorder fails.
