* 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.
