/// <summary>Creates a new font.</summary>
/// <remarks>
/// Creates a new font. This font can be one of the 14 built in types,
/// a Type1 font referred to by an AFM or PFM 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. A name is still required to identify
/// the font type.
/// <p/>
/// Besides the common encodings described by name, custom encodings
/// can also be made. These encodings will only work for the single byte fonts
/// Type1 and TrueType. The encoding string starts with a '#'
/// followed by "simple" or "full". If "simple" there is a decimal for the first character position and then a list
/// of hex values representing the Unicode codes that compose that encoding.<br />
/// The "simple" encoding is recommended for TrueType fonts
/// as the "full" encoding risks not matching the character with the right glyph
/// if not done with care.<br />
/// The "full" encoding is specially aimed at Type1 fonts where the glyphs have to be
/// described by non standard names like the Tex math fonts. Each group of three elements
/// compose a code position: the one byte code order in decimal or as 'x' (x cannot be the space), the name and the Unicode character
/// used to access the glyph. The space must be assigned to character position 32 otherwise
/// text justification will not work.
/// <p/>
/// Example for a "simple" encoding that includes the Unicode
/// character space, A, B and ecyrillic:
/// <PRE>
/// "# simple 32 0020 0041 0042 0454"
/// </PRE>
/// <p/>
/// Example for a "full" encoding for a Type1 Tex font:
/// <PRE>
/// "# full 'A' nottriangeqlleft 0041 'B' dividemultiply 0042 32 space 0020"
/// </PRE>
/// </remarks>
/// <param name="name">the name of the font or its location on file</param>
/// <param name="font">the true type font or the afm in a byte array</param>
/// <param name="cached">
/// true if the font comes from the cache or is added to
