KJK::Hyperion 8c7bebfed8 - test GetTextFaceW instead of GetTextFaceA
- test that:
    - the last error is never set
    - the buffer size is ignored if the buffer is NULL
    - the buffer size is returned if the buffer is non-NULL and too small
    - the function fails if a non-NULL buffer has a size <= 0
 - allocate the DC for a GDI test with a GDI routine (CreateCompatibleDC) instead of an USER routine (GetDC)
