/*
* This script was developed by the Einfach für Alle web site (http://www.einfach-fuer-alle.de/artikel/fontsize/).
* The version below was slightly modified to include a reset button (original script has only bigger and smaller)
* It was also modified to move some parts to the TYPO3 plugin so that they could be written dynamically
* (for example the control buttons can be created using IMAGE content objects)
