gtk/gtkdnd.c (_gtk_drag_source_handle_event) Remove use of

Browse Source 
Sun Jul  6 13:00:20 2003  Owen Taylor  <otaylor@redhat.com>

        * gtk/gtkdnd.c (_gtk_drag_source_handle_event)
        * gtk/gtkdnd.c (gtk_drag_begin_internal):  Remove use
        of GDK_POINTER_MOTION_HINT_MASK.

        * gtk/gtkdnd.c (gtk_drag_update_idle): Move updating
        of the drag into an idle as a superior form of
        expose compression.

        * gtk/gtkdnd.c (gtk_drag_begin_internal): Move default icon
        creation here, so that we have an icon at the start
        of the drag (e.g., when retrieving the window cache
        information.)
