    pybootchartgui/draw.py: allow moving process chart up and down
    
    Substracting curr_y when determining the hight of the process chart is
    wrong because the height is independent of the position where the
    chart is about to be drawn. It happens to work at the moment because
    curr_y is always 10 when render_processes_chart() gets called. But it
    leads to a negative height when other charts are drawn above it, and
    then the grid gets drawn on top of those other charts.
    
    Substracting some constant is relevant because otherwise the box is
    slightly larger than the process bars. Not sure exactly where that
    comes from (text height?); leg_s seems a suitable constant and happens
    to be 10, so everything still gets rendered exactly as before.
