    app: add prepare-to-remove-slider signal to GimpToolLine · 50acb669
    Ell authored
    The signal is emitted when a slider is dragged away from the line,
    and will be removed when the button is released, and when the
    slider is dragged back to the vicinity of the line, and won't be
    removed.  The last parameter of the signal is a boolean flag
    differentiating between the two cases.
    Note that a remove-slider signal may be emitted without a preceeding
    prepare-to-remove-slider signal, however, is a prepare-to-remove-
    slider signal is emitted with a TRUE last parameter, it must be
    eventually followed by a remove-slider signal, or by another
    prepare-to-remove-slider signal with a FALSE last parameter.
