- Add support for GGO_BEZIER and a few bug fixes for GGO_NATIVE. - Much better support for non ansi charsets in font matching. - Proper implementation of GetTextFace for gdi font. - Load fonts that are listed in the registry but aren't in %WINDOWSDIR%\fonts. - Revert TranslateCharsetInfo to use codepage 1252 with ANSI_CHARSET. - Add support for VIETNAMESE_CHARSET and SYMBOL_CHARSET.
