\description{
  These functions handle the translation of a device-independent R graphics
  font family name to a windows font description.
}
\usage{
windowsFont(family)

windowsFonts(...)
}
\arguments{
  \item{family}{a character vector containing the font family name
    (\code{"TT"} as the first two characters indicates a TrueType font).
  }
  \item{\dots}{either character strings naming mappings to display,
    or new (named) mappings to define.}
}
\details{
  A windows device is created with a default font (see
  the documentation for \code{windows}), but it is also possible
  to specify a font family when drawing to the device (for example, see
  the documentation for \code{"family"} in \code{\link{par}} and for
  \code{"fontfamily"} in \code{\link{gpar}} in the \pkg{grid} package).

  The font family sent to the device is a simple string name, which must be
  mapped to something more specific to windows fonts.  A list of
  mappings is maintained and can be modified by the user.

  The \code{windowsFonts} function can be used to list existing
  mappings and to define new mappings.  The \code{windowsFont}
  function can be used to create a new mapping.

  Default mappings are provided for three device-independent font family
  names: \code{"sans"} for a sans-serif font, \code{"serif"} for a serif
  font and \code{"mono"} for a monospaced font.

  These mappings will only be used if the current font face is
  1 (plain), 2 (bold), 3 (italic), or 4 (bolditalic).
