/**
* Create the PDF canvas.
*
* Parameters available:
*
* 'page' Specify the page/paper format for the graph's page, available
* formats are: A0, A1, A2, A3, A4, A5, A6, B5, letter, legal, ledger,
* 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
*
* 'pdf' An existing PDFlib PDF document to add the page to
*
* 'add_page' (true/false) Used together with 'pdf', to specify whether the
* canvas should add a new graph page (true) or create the graph on the
* current page (false), default is 'true'
*
* 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
* effect.
*
* 'left' and 'top' are overridden by 'align'
*
* It is required either to specify 'width' & 'height' or 'page'.
*
* The PDF format/PDFlib has some limitations on the capabilities, which
* means some functionality available using other canvass (fx. alpha
* blending and gradient fills) are not supported with PDF (see Canvas.txt
* in the docs/ folder for further details)
*
* @param array $param Parameter array
