        Bug 9560: should support new CSS3 cursor types to get more resizing directions
        http://bugzilla.opendarwin.org/show_bug.cgi?id=9560

        Adds support for ew-resize, ns-resize, nesw-resize, nwse-resize,
        col-resize and row-resize CSS3 cursor values.

        Also converted some of the cursor images to grayscale tiffs,
        some were RGB but had no color data.
