[GDI32_APITEST]: GetGlyphIndices: Have fun & make ReactOS BSoD from user-mode! More
seriously, test extra cases of this API, and show that our current implementation
certainly is incomplete & prone to bugs.
The particular case "GetGlyphIndicesW(hdc, NULL, 0, NULL, 0)" is used by Word
2010 (and other apps) when opening the font combolist, and seems to be undocumented.
