/** 
 * The Font class represents fonts, which are used to
 * render text in a visible way.
 * A font provides the information needed to map sequences of
 * characters to sequences of glyphs
 * and to render sequences of glyphs on Graphics and
 * Component objects.
 * 
 * 
Characters and Glyphs
 * 
 * A character is a symbol that represents an item such as a letter,
 * a digit, or punctuation in an abstract way. For example, 'g',
 * LATIN SMALL LETTER G, is a character.
 * 

 * A glyph is a shape used to render a character or a sequence of
 * characters. In simple writing systems, such as Latin, typically one glyph
 * represents one character. In general, however, characters and glyphs do not
 * have one-to-one correspondence. For example, the character 'á'
 * LATIN SMALL LETTER A WITH ACUTE, can be represented by
 * two glyphs: one for 'a' and one for '´'. On the other hand, the
 * two-character string "fi" can be represented by a single glyph, an
 * "fi" ligature. In complex writing systems, such as Arabic or the South
 * and South-East Asian writing systems, the relationship between characters
 * and glyphs can be more complicated and involve context-dependent selection
 * of glyphs as well as glyph reordering.
 *
 * A font encapsulates the collection of glyphs needed to render a selected set
 * of characters as well as the tables needed to map sequences of characters to
 * corresponding sequences of glyphs.
 *
 * 
Physical and Logical Fonts
 *
 * The Java 2 platform distinguishes between two kinds of fonts:
 * physical fonts and logical fonts.
 * 

 * Physical fonts are the actual font libraries containing glyph data
 * and tables to map from character sequences to glyph sequences, using a font
 * technology such as TrueType or PostScript Type 1.
 * 
 * Physical fonts may use names such as Helvetica, Palatino, HonMincho, or
 * any number of other font names.
 * Typically, each physical font supports only a limited set of writing
 * systems, for example, only Latin characters or only Japanese and Basic
 * Latin.
 * The set of available physical fonts varies between configurations.
 * 
 * 

 * Logical fonts are the five font families defined by the Java
 * platform which must be supported by any Java runtime environment:
 * Serif, SansSerif, Monospaced, Dialog, and DialogInput.
 * These logical fonts are not actual font libraries. Instead, the logical
 * font names are mapped to physical fonts by the Java runtime environment.
 * The mapping is implementation and usually locale dependent, so the look
 * and the metrics provided by them vary.
 * Typically, each logical font name maps to several physical fonts in order to
 * cover a large range of characters.
 * 

 * 
 * 

 * For a discussion of the relative advantages and disadvantages of using
 * physical or logical fonts, see the
 * Internationalization FAQ
 * document.
 *
 * 
Font Faces and Names
 * 
 * A Font 
 * can have many faces, such as heavy, medium, oblique, gothic and
 * regular. All of these faces have similar typographic design.
 * 

 * There are three different names that you can get from a 
 * Font object.  The logical font name is simply the
 * name that was used to construct the font.
 * The font face name, or just font name for
 * short, is the name of a particular font face, like Helvetica Bold. The
 * family name is the name of the font family that determines the
 * typographic design across several faces, like Helvetica.
 * 

 * The Font class represents an instance of a font face from
 * a collection of  font faces that are present in the system resources
 * of the host system.  As examples, Arial Bold and Courier Bold Italic
 * are font faces.  There can be several Font objects
 * associated with a font face, each differing in size, style
 *  and font features.  
 *
