    Make w3mimgdisplay work with st

    Before this patch draw() calls drawregion which calls xdraws and then
    updates whole window in one call thus overdrawing anything drawn by
    w3mimgdisplay. After moving XCopyArea to xdraws it only updates the
    regions which are being updated by XftDraw* functions. It may do a few
    more calls to XCopyArea with this patch.
