/**
   A fontset is an entire Alphabet (256 entries) of one font.
   It is made by creating a file containing a matrix with 256
   little pictures in it, displaying the letters of this alphabet.
   Then these letters are projected onto Quads, which can be aranged
   in a sorted order, to display some text

   usage:
   1. initialize the Class by loading the source-font-picture
   2. set the size
   3. write some text with printText
   4. delete the class again.
