/**
 * ( begin auto-generated from beginRecord.xml )
 *
 * Opens a new file and all subsequent drawing functions are echoed to this
 * file as well as the display window. The <b>beginRecord()</b> function
 * requires two parameters, the first is the renderer and the second is the
 * file name. This function is always used with <b>endRecord()</b> to stop
 * the recording process and close the file.
 * <br /> <br />
 * Note that beginRecord() will only pick up any settings that happen after
 * it has been called. For instance, if you call textFont() before
 * beginRecord(), then that font will not be set for the file that you're
 * recording to.
 *
