    app: don't show context menu in compact spin scale without focus
    
    Always enter relative adjustment mode when right-clicking an
    unfocused compact GimpSpinScale, instead of showing the context
    menu, since it otherwise leaves little room to enter relative mode
    in narrow spin scales.  The context menu can still be activated for
    focused spin scales.
