-     * 11x17, cd_front, inlay, inlay_nosides

-     * 'align' Alignment of the graph on the page, available options are:
-     * topleft, topcenter, topright, leftcenter, center, rightcenter,
-     * leftbottom, centerbottom, rightbottom
-     *
-     * 'orientation' Specifies the paper orientation, default is 'portrait' and
-     * 'landscape' is also supported.
-     *
-     * 'creator' The creator tag of the PDF/graph
-     *
-     * 'author' The author tag of the PDF/graph
-     *
-     * 'title' The title tag of the PDF/graph

-     * 'width' The width of the graph on the page

-     * 'height' The height of the graph on the page

-     * 'left' The left offset of the graph on the page
-     *
-     * 'top' The top offset of the graph on the page

-     * 'filename' The PDF file to open/add page to, using 'filename' requires
-     * the commercial version of PDFlib (http://www.pdflib.com/), this has for
-     * obvious ($ 450) reasons not been tested
-     *

-     *
-     * 'add_page' (true/false) Used together with 'pdf', to specify whether the

-     *
-     * The 'page' and 'width' & 'height' can be mutually omitted, if 'page' is
-     * omitted the page is created using dimensions of width x height, and if
-     * width and height are omitted the page dimensions are used for the graph.

-     * If 'pdf' is specified, 'filename', 'creator', 'author' and 'title' has no

- * The class is quick, simple to use, and does its job fairly well but it's got
- * some code smells:
- *  - Call setColors() for some functions but not others.
- *  - Different functions expect different color formats. setColors() only
- *    accepts hex while allocateColor() will accept named or hex (provided the
- *    hex ones start with the # character).
- *  - Some conversions go in only one direction, ie HSV->RGB but no RGB->HSV.

-/**
- * 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!)

-/**
- * Format data as looked up in an array.
- *
- * ArrayData is useful when a numercal value is to be translated to
- * something thats cannot directly be calculated from this value, this could for
- * example be a dataset meant to plot population of various countries. Since x-
- * values are numerical and they should really be country names, but there is no
- * linear correlation between the number and the name, we use an array to 'map'
- * the numbers to the name, i.e. $array[0] = 'Denmark'; $array[1] = 'Sweden';
- * ..., where the indexes are the numerical values from the dataset. This is NOT
- * usefull when the x-values are a large domain, i.e. to map unix timestamps to
- * date-strings for an x-axis. This is because the x-axis will selecte arbitrary
- * values for labels, which would in principle require the ArrayData to hold
- * values for every unix timestamp. However ArrayData can still be used to solve
- * such a situation, since one can use another value for X-data in the dataset
- * and then map this (smaller domain) value to a date. That is we for example
- * instead of using the unix-timestamp we use value 0 to represent the 1st date,
- * 1 to represent the next date, etc.

- * Plot area used for map plots.
- *
- * A map plot is a chart that displays a map (fx. a world map) in the form of  .
- * png file. The maps must be located in the /Images/Maps folder and a
- * corresponding .txt files mush also exist in this location where named
- * locations are mapped to an (x, y) coordinate of the map picture (this text
- * file is tab separated with 'Name' 'X' 'Y' values, fx 'Denmark 378 223'). The
- * x-values in the dataset are then the named locations (fx 'Denmark') and the
- * y-values are then the data to plot. Currently the best (if not only) use is
- * to combine a map plot area with a {@link Image_Graph_Plot_Dot} using {@link
- * Image_Graph_Marker_PercentageCircle} as marker.
