Log:
[WIN32K] / [GDI32]
- GetTextExtentExPointI and GetTextExtentPointI take an array of glyph indices, not
characters. Pass a flag GTEF_INDICES (This is a reactos specific definition and not
exactly like on Windows XP, but the real names/values are undocumented and this is the
easiest way.) to NtGdiGetTextExtent/NtGdiGetTextExtentExW and handle this flag in
TextIntGetTextExtentPoint to account for this.
