    Qt: Improve tcptrace graph drag responsiveness
    
    Subclass QCPErrorBars with implementation that never accepts clicks.
    This prevents a lot of square root computations in QCustomPlot
    mousePressEvent handle and results in usable tcptrace graph.
    
    An alternative solution to the poor performance problem could be using
    QCP::srmCustom SelectionRectMode. I don't know how to implement graph
    drag with QCP::srmCustom, and thus I went with simple subclass approach.
