// Amazingly, GetThemeFont() and GetThemeSysFont() functions use LOGFONTA under

// If we declare them as taking LOGFONT below, the code would be able to
// silently pass LOGFONTA to them in ANSI build and would crash at run-time
// under Windows Vista/7 because of a buffer overrun (LOGFONTA being smaller
// than LOGFONTW expected by these functions). If we we declare them as taking
// LOGFONTW, the code wouldn't work correctly under XP. So we use a special
