2008-09-01 Esteban Sanchez <estebans@artica.es> 

* reporting/pandora_graph.php: Added to repository. New abstract class
	PandoraGraphAbstract to allow the change of the graphic engine easily.

	* reporting/fgraph.php: Rewritten to remove all the references to
	PEAR::Image and replaced by the new Pandora Graph abstract class.

	* reporting/pearimage_graph.php: Added to repository. Implements
	PandoraGraphAbstract class with the PEAR::Image functions.
