A lot of changed, nothing complete. Just committing so I can transfer location. I'm currently focusing on getting SFML::Image complete since the entire library more or less depends on it.

/* Class for loading and manipulating character fonts.
*
* Fonts can be loaded from a file or from memory, from the most common types of fonts.
*
* See the loadFromFile method for the complete list of supported formats.
*
* Once it is loaded, a SFML::Font instance provides three types of informations about the font:
*
* - Global metrics, such as the line spacing
* - Per-glyph metrics, such as bounding box or kerning
* - 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 SFML::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 SFML::Text is a lightweight object which can combine the glyphs data and metrics of a SFML::Font to display any text
* on a render target. Note that it is also possible to bind several SFML::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 SFML::Font must not be destructed while it is used by a SFML::Text (i.e. never write a function that uses
* a local SFML::Font instance for creating a text).
*
* Usage example:
*
* # Declare a new font
* font = SFML::Font.new
*
* # Load it from a file
* if font.LoadFromFile("arial.ttf") == false
* # error...
* end
*
* # Create a text which uses our font
* text1 = SFML::Text.new
* text1.setFont( font )
* text1.setCharacterSize( 30 )
* text1.setStyle( sf::Text::Regular )
*
* # Create another text using the same font, but with different parameters
* text2 = SFML::Text.new
* text2.setFont( font )
* text2.setCharacterSize( 50 )
* text2.setStyle( SFML::Text::Italic )
*
* Apart from loading font files, and passing them to instances of SFML::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.
