////////////////////////////////////////////////////////////
/// \class sf::Text
/// \ingroup graphics
///
/// sf::Text is a drawable class that allows to easily display
/// some text with custom style and color on a render target.
///
/// It inherits all the functions from sf::Transformable:
/// position, rotation, scale, origin. It also adds text-specific
/// properties such as the font to use, the character size,
/// the font style (bold, italic, underlined, strike through), the
/// global color and the text to display of course.
/// It also provides convenience functions to calculate the
/// graphical size of the text, or to get the global position
/// of a given character.
///
/// sf::Text works in combination with the sf::Font class, which
/// loads and provides the glyphs (visual characters) of a given font.
///
/// The separation of sf::Font and sf::Text 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.
///
/// 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).
///
/// See also the note on coordinates and undistorted rendering in sf::Transformable.
///
/// Usage example:
/// \code
/// // Declare and load a font
/// sf::Font font;
/// font.loadFromFile("arial.ttf");
///
/// // Create a text
/// sf::Text text("hello", font);
/// text.setCharacterSize(30);
/// text.setStyle(sf::Text::Bold);
/// text.setColor(sf::Color::Red);
///
/// // Draw it
/// window.draw(text);
/// \endcode
///
/// \see sf::Font, sf::Transformable
///
