/// \class sf::Font
/// \ingroup graphics
///
/// Fonts can be loaded from a file, from memory or from a custom
/// stream, and supports the most common types of fonts. See
/// the loadFromFile function for the complete list of supported formats.
///
/// Once it is loaded, a sf::Font instance provides three
/// types of information about the font:
/// \li Global metrics, such as the line spacing
/// \li Per-glyph metrics, such as bounding box or kerning
/// \li Pixel representation of glyphs
///
/// Fonts alone are not very useful: they hold the font data
/// but cannot make anything useful of it. To do so you need to
/// use the sf::Text class, which is able to properly output text
/// with several options such as character size, style, color,
/// position, rotation, etc.
/// This separation allows more flexibility and better performances:
/// indeed a sf::Font is a heavy resource, and any operation on it
/// is slow (often too slow for real-time applications). On the other
/// side, a sf::Text is a lightweight object which can combine the
/// glyphs data and metrics of a sf::Font to display any text on a
/// render target.
/// Note that it is also possible to bind several sf::Text instances
/// to the same sf::Font.
///
/// It is important to note that the sf::Text instance doesn't
/// copy the font that it uses, it only keeps a reference to it.
/// Thus, a sf::Font must not be destructed while it is
/// used by a sf::Text (i.e. never write a function that
/// uses a local sf::Font instance for creating a text).
///
/// Usage example:
/// \code
/// // Declare a new font
/// sf::Font font;
///
/// // Load it from a file
/// if (!font.loadFromFile("arial.ttf"))
/// {
/// // error...
/// }
///
/// // Create a text which uses our font
/// sf::Text text1;
/// text1.setFont(font);
/// text1.setCharacterSize(30);
/// text1.setStyle(sf::Text::Regular);
///
/// // Create another text using the same font, but with different parameters
/// sf::Text text2;
/// text2.setFont(font);
/// text2.setCharacterSize(50);
/// text2.setStyle(sf::Text::Italic);
/// \endcode
///
/// Apart from loading font files, and passing them to instances
/// of sf::Text, you should normally not have to deal directly
/// with this class. However, it may be useful to access the
/// font metrics or rasterized glyphs for advanced usage.
///
/// Note that if the font is a bitmap font, it is not scalable,
/// thus not all requested sizes will be available to use. This
/// needs to be taken into consideration when using sf::Text.
/// If you need to display text of a certain size, make sure the
/// corresponding bitmap font that supports that size is used.
///
/// \see sf::Text
