[hyperion] 36779: - 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)

Log:
 - 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)
