    // This sample shows the simplest way to render a web page
    // specified by a URL to a PDF (here we render the Google home page).
    //
    // In this sample we directly use the GcHtmlRenderer class
    // to render the page to a temporary PDF file, which is then
    // returned in the output stream.
    // A more flexible way that allows to easily add HTML conetnt
    // to a PDF file along with other content is via the extension
    // methods GcPdfGraphics.MeasureHtml()/GcPdfGraphics.DrawHtml()
    // as demonstrated by HelloWorldHtml and other samples.
    //
    // Please see notes in comments at the top of HelloWorldHtml
    // sample code for details on adding GcHtml to your projects.
