			plus one of the following options:
 | 
 | 
		Display the page designated by page, with its contents magnified just enough to
		fit the entire page within the window both horizontally and vertically. If the
		required horizontal and vertical magnification factors are different, use the
		smaller of the two, centering the page within the window in the other dimension.
 | 
 | 
		Display the page designated by page, with the vertical coordinate top positioned
		at the top edge of the window and the contents of the page magnified just enough
		to fit the entire width of the page within the window.
 | 
 | 
		Display the page designated by page, with the horizontal coordinate left positioned
		at the left edge of the window and the contents of the page magnified just enough
		to fit the entire height of the page within the window.
 | 
 | 
		-fitr => [ $left, $bottom, $right, $top ]
 | 
 | 
		Display the page designated by page, with its contents magnified just enough to
		fit the rectangle specified by the coordinates left, bottom, right, and top

		Display the page designated by page, with the vertical coordinate top
		positioned at the top edge of the window and the contents of the page
		magnified just enough to fit the entire width of its bounding box
		within the window.

 | 
 | 
		Display the page designated by page, with the coordinates (left, top) positioned
		at the top-left corner of the window and the contents of the page magnified by
