    Bug 795177 - seg fault with clone tool
    
    Don't flush the source pickable in gimp_source_core_motion(), as
    this introduces a race condition between the paint thread and the
    display-update timeout, when the source pickable is the image
    containing the target drawable.
    
    Flushing the source pickable shouldn't be currently necessary, and
    either way, should happen during initialization.
