1042 to make a match between the font requested and\r
1043 the font available. The caller must guarantee\r

1998 If NULL, then the current system language is\r

2001 including the color and font. If NULL, then the\r
2002 string will be output in the default system font\r
2003 and color.\r
2004 @param Blt If this points to a non-NULL on entry, this\r
