-/**
- * Main class for the graph creation.
- *
- * This is the main class, it manages the canvas and performs the final output
- * by sequentialy making the elements output their results. The final output is
- * handled using the {@link Image_Canvas} classes which makes it possible
- * to use different engines (fx GD, PDFlib, libswf, etc) for output to several
- * formats with a non-intersecting API.
- *
- * This class also handles coordinates and the correct managment of setting the
- * correct coordinates on child elements.

-     * Image_Graph [Constructor].
-     *
-     * If passing the 3 parameters they are defined as follows:'
-     * 
-     * Fx.:
-     * 
-     * $Graph =& new Image_Graph(400, 300);
-     * 
-     * or using the factory method:
-     * 
-     * $Graph =& Image_Graph::factory('graph', array(400, 300));
-     * 
-     * This causes a 'png' canvas to be created by default. 
-     * 
-     * Otherwise use a single parameter either as an associated array or passing
-     * the canvas along to the constructor:
-     *
-     * 1) Create a new canvas with the following parameters:
-     *
-     * 'canvas' - The canvas type, can be any of 'gd', 'jpg', 'png' or 'svg'
-     * (more to come) - if omitted the default is 'gd'
-     *
-     * 'width' - The width of the graph
-     *
-     * 'height' - The height of the graph
-     * 
-     * An example of this usage:
-     * 
-     * $Graph =& Image_Graph::factory('graph', array(array('width' => 400,
-     * 'height' => 300, 'canvas' => 'jpg')));
-     * 
-     * NB! In thïs case remember the "double" array (see {@link Image_Graph::
-     * factory()})
-     * 
-     * 2) Use the canvas specified, pass a valid Image_Canvas as
-     * parameter. Remember to pass by reference, i. e. &amp;$canvas, fx.:
-     *
-     * $Graph =& new Image_Graph($Canvas);
-     *
-     * or using the factory method:
-     *
-     * $Graph =& Image_Graph::factory('graph', $Canvas));
-     *
-     * @param mixed $params The width of the graph, an indexed array
-     * describing a new canvas or a valid {@link Image_Canvas} object
-     * @param int $height The height of the graph in pixels
-     * @param bool $createTransparent Specifies whether the graph should be
-     *   created with a transparent background (fx for PNG's - note: transparent
-     *   PNG's is not supported by Internet Explorer!)
