    theme: Make spinner drawing start with the solid line
    
    Previously, for i == 0, we were drawing the translucent line first.
    However, people reading the code would always assume the solid line is
    indicated by the current step. So make the code do that.
    
    Note that the spinner now rotates in the wrong direction. This will be
    fixed in a future commit.
