	* src/print-preview.c (PreviewMode): Renamed the move modes to
	MODE_MOVE and MOVE_MODE_DRAGGING.
	(preview_canvas_button_press): Split the event handling code
	between several functions.  Rationale:  we will want drag-zoom and
	we need different modes for this, and the code in a single
	function would get unwieldy.  In addition, grab the pointer and
	use GDK_POINTER_MOTION_HINT_MASK for better behavior.
	(PrintPreview): Added fields for drag anchor and drag offset.
	(drag_to): New function to drag/scroll.
	(create_preview_canvas): Connect to the different event handlers.
	(do_zoom): We do not need to re-render the page; just set the zoom
	factor.  Also, use exponential zooming for better behavior.

	* src/cursors.h: Moved the cursor #defines to an enum.  This way
	we can check for a max value in cursor_get().  Moved the cursor
	array to the .c file and made it private.

	* src/cursors.c (cursors_init): Added sanity check so that all
	cursors are defined.
	(cursor_get): New function to get a cursor based on its type.
	(cursors): Added hand cursors.

	* src/pixmaps/cursor_hand_{open,closed}.xpm: Added hand cursors.
