  *  Definition of textEngine, the Font and the Text

    Text is the text outputed.
    Font is a class that loads a certain ttf-file with a specific height into memory
    TextEngine is used to manage the all the different Fonts that might be included

    for more information see the specific classes.

    !! IMPORTANT !! When using ttf fonts clear the license issues prior to
   adding them to orxonox. This is really important, because we do not want
   to offend anyone.
