plbop: Begin a new page

DESCRIPTION:

	Begins a new page.	For a file driver, the output file is opened if
	necessary.	Advancing the page via pleop and plbop is useful when a
	page break is desired at a particular point when plotting to subpages.
	 Another use for pleop and plbop is when plotting pages to different
	files, since you can manually set the file name (or file handle) by
	calling plsfnam or plsfile after the call to pleop (in fact some
	drivers may only support a single page per file, making this a
	necessity).  One way to handle this case automatically is to page
	advance via pladv, but enable familying (see plsfam) with a small byte
	per file limit so that a new family member file will be created on
	each page break.
