/** Creates a new font. This font can be one of the 14 built in types,
* a Type1 font referred by an AFM file, a TrueType font (simple or collection) or a CJK font from the
* Adobe Asian Font Pack. TrueType fonts and CJK fonts can have an optional style modifier
* appended to the name. These modifiers are: Bold, Italic and BoldItalic. An
* example would be "STSong-Light,Bold". Note that this modifiers do not work if
* the font is embedded. Fonts in TrueType collections are addressed by index such as "msgothic.ttc,1".
* This would get the second font (indexes start at 0), in this case "MS PGothic".
* <P>
* The fonts may or may not be cached depending on the flag <CODE>cached</CODE>.
* If the <CODE>byte</CODE> arrays are present the font will be
* read from them instead of the name. The name is still required to identify
* the font type.
* @param name the name of the font or it's location on file
* @param encoding the encoding to be applied to this font
* @param embedded true if the font is to be embedded in the PDF
* @param cached true if the font comes from the cache or is added to
* the cache if new. false if the font is always created new
* @param ttfAfm the true type font or the afm in a byte array
* @param pfb the pfb in a byte array
* @return returns a new font. This font may come from the cache but only if cached
* is true, otherwise it will always be created new
* @throws DocumentException the font is invalid
* @throws IOException the font file could not be read
