[gtk+/client-side-decorations: 59/92] Make resize handles larger



commit 6cb831b9edc0c0fa4fb048564ca918c7901c125c

    Make resize handles larger
    
    There is now a ::decoration-resize-handle style property to control
    the size of these handles; also clean up some confusion where the old
    window->frame_width was used.
