/**
 * There are three different font faces available in MIDP:
 * Monospace, Proportional, and System. There are eight 
 * different styles available: Plain, Italic, Bold, Bold Italic,
 * Underline, Underline Italic, Underline Bold, and 
 * Underline Bold Italic. There are three different sizes 
 * available: Small, Medium, and Large. That presents
 * a matrix of 72 different font possibilities. This class
 * serves to manage those different possibilities.
 *
 * Identifiers use a FACE_STYLE_SIZE naming scheme, where
 * FACE is one of [MONO|PROP|SYS], STYLE is one of 
 * [P|I|B|BI|U|UI|UB|UBI], and SIZE is one of [S|M|L].
